The most important thing ever about your website is that it has to stay online. Clients visit it from every corner of the world, at any time. If they get to your site and it's not available they would probably not come come back in the future.
At SupportHost we offer an uptime guarantee, meaning that if we do not respect it we give you back the money. We guarantee an uptime from 99.5% to 99.9% depending on the king of hosting account you have with us.
What happens when a website is offline?
It can happen that a server has a problem, or your account has a problem. This problem may last from a few seconds to a few hours depending on its cause.
During this time you website will be offline, no one will be able to reach it. But something even worse can happen to your emails. If someone sends you an email while the server is offline they will get an error as if your email address does not exists at all. The email they send you will be lost and there will be no way to recover it, unless they send it again of course. In other words you will never receive that email, not even after your server comes back online.
This is what was happening until today. In the last few months we have had an uptime of 99.99%. Despite this we decided to introduce two secondary MX servers that are always active. They will receive your emails when the server that is hosting your website is offline, whatever the reason is.
So if the server hosting your website goes offline, one of these secondary server will receive your email and store them to up to 10 days. Once the server come back online all you emails will be sent to your account as if nothing happened.
This service is active for all our customers using our default nameservers:

The easiest way is to set our nameservers, and after the domain resolves to our cluster you can setup CloudFlare. MX records will be automatically imported by CloudFlare.
If you prefer to set them manually you need to add this two records in CloudFlare (for advanced users):
