Reasons for choosing Web Hosting in India based datacenteres

India has been emerging as a very big market in web hosting industry. With the localization of web services & websites the requirement for choosing web hosting in india is in increasing day by day. The web pages become more complex, referencing resources from numerous domains, DNS lookups can become a significant bottleneck in the browsing experience. Whenever a client needs to query a DNS resolver over the network, the latency introduced can be significant, depending on the proximity and number of nameservers the resolver has to query. For example, web hosting of your  website in India & US with same content, when you run the tracert command on your both of the website on command prompt then you will find out that US website will take 15 – 20 Hopes and Local Indian website takes only 3 – 5 Hopes to reach your website that means Indian website will take much lesser time to open than US website. Which indicates that having web hosting in india have its own advantages which includes latency reaons. too

There are two main components to DNS latency when you compare web hosting in India and else where.
* Latency between the client (user) and DNS resolving server. In most cases this is largely due to the usual round-trip time (RTT) constraints in networked systems: geographical distance between client and server machines; network congestion; web hosting packet loss and long retransmit delays (one second on average); overloaded servers, denial-of-service attacks and so on.

* Latency between resolving servers and other nameservers. This source of latency is caused primarily by the following factors:

1. Cache misses. If a response cannot be served from a resolver’s cache, but requires recursively querying other nameservers, the added network latency is considerable, especially if the authoritative servers are geographically remote.
2. Underprovisioning. If DNS resolvers are overloaded, they must queue DNS resolution requests and responses, and may begin dropping and retransmitting packets.
3. Malicious traffic. Even if a DNS service is overprovisioned, DoS traffic can place undue load on the servers. Similarly, Kaminsky-style attacks can involve flooding resolvers with queries that are guaranteed to bypass the cache and require outgoing requests for resolution.

We believe that the cache miss factor is the most dominant cause of DNS latency.

Cache misses
Even if a resolver has abundant local resources, the fundamental delays associated with talking to remote nameservers are hard to avoid. In other words, assuming the resolver is provisioned well enough so that cache hits take zero time on the server-side, cache misses remain very expensive in terms of latency. To handle a miss, a resolver has to talk to at least one, but often two or more external nameservers. Operating the Googlebot web crawler, we have observed an average resolution time of 130 ms for nameservers that respond. However, a full 4-6% of requests simply time out, due to UDP packet loss and servers being unreachable. If we take into account failures such as packet loss, dead nameservers, DNS configuration errors, etc., the actual average end-to-end resolution time is 300-400 ms. However, there is high variance and a long tail.

Though the cache miss rate may vary among DNS servers, cache misses are fundamentally difficult to avoid, for the following reasons:

* Internet size and growth. Quite simply, as the Internet grows, both through the addition of new users and of new sites, most content is of marginal interest. While a few sites (and consequently DNS names) are very popular, most are of interest to only a few users and are accessed rarely; so the majority of requests result in cache misses.

* Low time-to-live (TTL) values. The trend towards lower DNS TTL values means that resolutions need more frequent lookups.

* Cache isolation. DNS servers are typically deployed behind load balancers which assign queries to different machines at random. This results in each individual server maintaining a separate cache rather than being able to reuse cached resolutions from a shared pool.

For closed resolvers, this is not really an issue. For open resolvers, the closer your servers are located to your users, the less latency they will see at the client end. In addition, having sufficient geographical coverage can indirectly improve end-to-end latency, as nameservers typically return results optimized for the DNS resolver’s location. That is, if a content provider hosts mirrored sites around the world, that provider’s nameservers will return the IP address in closest proximity to the DNS resolver.

How to Manage Content Filtering

Content Filtering

Content filtering is an advanced method of performing actions on emails that meet specific criteria. For example, you can use content filters to delete messages with certain attachments, forward emails from a specific email address to another account, or even alter the subject of specific types of email. Content filtering is very open ended, in order to allow you to filter the way you want to.

To get started, click the Settings button on the main toolbar, and then select Content Filtering in the Filtering folder under the My Settings tree view.

Adding a Filter – Clicking the New Filter icon on the Action toolbar starts the Content Filter Wizard which is explained in more detail below.

Editing a Filter – Click on a filter’s row then click the Edit icon in the Action tool bar, or right click and select Edit .

Deleting a Filter – Click on a filter’s row then click the Delete icon in the Action tool bar, or right click and select Delete .

Deleting all Filters – Clicking the Delete All button will delete all content filters for your account. Once you confirm the action, it is not reversible.

Changing Filter Order – Content filters are executed in the order in which they show up in the list. When a content filter gets triggered and performs an action, no other content filtering is performed on that message. To change the order, click on the arrows next to a filter.
Content Filter Wizard

The New Content Filter wizard is three pages long, and it will walk you through each step necessary to create the filter.

Step 1 – Filter Criteria

In this step of the wizard, choose the type of things that the filter will look at. Possible filter criteria types are listed at the end of this help topic. Multiple criteria can be chosen, and you can choose in the next step whether all criteria must be met, or only one of the criteria for the filter to activate.

Step 2 – Filter Type and Criteria Details

Choose whether this filter requires one criterion to be met from each and every section, or just one of the criteria in any section to be met, before an action is performed. Then choose whether you will be using any wildcards in your search strings. Usually, wildcards will not be necessary, but there are times when some people may want them.

For each of the criteria you chose in step 1, you will be able to enter details. Many types of content filters allow lists of items to be entered in, and these will be indicated. For example, if you chose to filter on From Address, you can enter multiple email addresses in the box (one per line) and if a message is from any of them, that criteria will be met.

You also have the ability to reverse the logic of a specific criteria item by changing the “matches” box to “does not match.”

Step 3 – Rule and Actions

A summary of your content filter rule will appear near the top of the page. Check that it is filtering the way you intend, and enter a name for the rule so that you can easily identify it later.

Choose one or more actions to take when a message matches this filter. The available actions are explained below:

* Delete message – Deletes the message so that it will never arrive at your Inbox. Messages deleted through content filtering are not recoverable.
* Bounce message – Sends a message back to the sender of the email saying that the message was bounced. Note that the message is still delivered to you unless you choose to delete it as well. Note: If the system administrator has disabled bouncing, this option will function the same as the delete action.
* Move message to folder – Delivers the incoming message to the folder you choose from the drop-down list. If you later delete that folder and leave the content filter active, the filter will automatically create the folder when the action is triggered.
* Prefix subject with comment – Useful for categorizing emails, the subject line will be altered to include the text you specify in the Comment box.
* Embed header line into message – Includes an email header into the message, which can be useful when performing additional filtering through Outlook or another email client. Headers should be formatted like “X-someheadername: value”
* Copy message – Forwards a copy of the message to another email address and leaves a copy of the message in your account as well.
* Reroute message to another email address – Forwards the message to another email address instead of this one. Will not store a copy of the email in your own account.

Sharing in RightMX Enterprise

Shared Objects Overview

RightMX Enterprise allows you to share resources like calendars with other users of your domain. The types of items that can be shared include:

* E-Mail Folders
* Contacts
* Calendars
* Task Lists
* Notes

Items that you are sharing with others are called Shared Resources. Items you are connected to on others’ accounts are called Mapped Resources.
Shared Resources

Sharing a resource, such as a calendar or e-mail folder, will allow the users you specify to access the resource with a pre-determined permission level.

To share a resource (in this example your calendar), follow the steps below:

1. To get started, click the Settings button on the main toolbar, and then select Shared Resources in the Sharing folder under the My Settings tree view.
2. Click on the New icon in the Actions toolbar.
3. Select who you would like to Share with
* User – A user is a single person on your domain.
* Group – A group is a set of users that fall under a similar department, permission level, or role. Your domain administrator can add and modify these user groups.
4. Choose an access level:
* None – This resource is not shared with the user. This setting is useful if you give permissions to a group but want a specific user to be denied permission.
* Availability-Only (Calendars only) – This setting is used to show availability for you if the user clicks on the availability link when adding a calendar item. Other than this functionality, the calendar acts as if it is not shared.
* Read-Only – Grants view access to the resource, which lets the other user see your information, without granting any permission to change or modify the resource in any way.
* Full Control – The user that has this permission can do everything on the resource that you can, including moving items, changing things, and even deleting information.
5. Save the user or group and repeat the process as needed. More than one user can be added at a time by putting each username on a separate line.

Note: The steps are very similar for each of the resource types. Just make sure you are viewing the resource you want to share when you click on the Sharing button.

Mapped Resources

RightMX Enterprise allows you to connect to resources (calendars, e-mail folders, etc) that have been shared to you by other users on your domain. To connect to a shared resource, perform the following steps:

1. To get started, click the Settings button on the main toolbar, and then select Mapped Resources in the Sharing folder under the My Settings tree view.
2. You will be presented with a list of all currently attached resources.
3. You can search for resources by name, or find one in the list and click on the Attach button.
4. Enter a friendly name for the resource and click the Save icon.

The resource will now be available in the sidebar.

If you wish to detach from a resource, go into Open Shared Resources and click on the Detach link next to the item.

Favorites

Report Favorites gives a user the ability to define certain criteria for reports that they will run on a regular basis. Once a chart is located that you would like to save, click the Add Favorites icon from the actions tool.

After clicking the Add Favorites icon, a window will pop up asking you to name your saved report and to populate the chart fields. Chart Definitions Once all fields are completed to your satisfaction, click OK at the bottom of the pop up window.

To access one of your Favorites at anytime, click the report from under the Favorites in the left tree view.
