Every once in a while, our server will do something stupid. Maybe a log file got too big and ate up all the disk space, or a process has hung. In either case, the result is our website is down. And in e-commerce, downtime = lost sales.
All of the issues I can easily fix in 15 minutes or less. But the issues never occur when it's convenient. It's always 4am, or when you're on vacation, etc.
Our company is small and can't afford another IT person/server admin/etc.
What we would like to do is find a company that provides 24/7 emergency server support on a contract basis. A non-technical employee can call them up and say "the site is down", and they'll log into your server and troubleshoot the problem within 15 minutes or so.
We don't need installation or removal of software, routine upgrades, or configuration. Just someone who's always available to fix problems quickly in an emergency when I'm not available.
Does such a service exist? Where might we find it?
Clarification: We're using a VPS provider that maintains the hardware and network infrastructure for us. But the don't provide os or software level support. Were looking for a company that can fix software or OS issues remotely via ssh, on a contract basis.
