Web Hosting Talk : Web Hosting Main Forums : Web Hosting : Any replicated/fault tolerant email service?

[albatroz]

I wonder if someone knows of such a service
that could assure 100% uptime service thanks
replication/fault tolerance.

Hello,

even with load balancing and redundant everything, you are not going to achieve 100% uptime.

We had 100% uptime on our mail server setup with load balancing since December, then our DC performed some maintenance and scheduled an outage, and there goes that

I guess you could cluster across Data Centers and get closer to 100%, but that would be cost prohibitive and still would not ensure 100%.

You should probably aim for 99.99% mail uptime, which is certainly achievable - but, the provider needs to put ALOT of effort into achieving that record over a prolonged period of time. Having said this, it is completely possible to have a very close to 0% mail loss - so, even if the service is down, mail is getting spooled. This is something that is attainable.

Cartika is right on the uptime, but you can "potentially" achieve 0% mail loss.

Simply find a company with Redundant Mail servers in multiple locations.

Redundant Mail servers doesn't mean you will have access to them, so if the primary goes down for some reason you may not be able to check your mail but the mail will still be going through and you will eventually get it when the primary mail server comes back up.

Check out www.webmail.us, they have a pretty rock solid setup.

I'll third on webmail.us. My renewel notice for my third year with them recently came up and I happily renewed. There service has been great and I have never known of any email lost through them in the time I've been with them. It's why I use them for email I know I want to receive.
