I've been with one host for geez like 8 years or so. It seems like I always get these intermittent "burps". That is, every once in awhile (maybe 2-4 times a day?) while working on e-mail or updating the website, I get "Server Not Found" errors or "Can't connect to mysql" errors. *Usually* they last for a few seconds and a simple refresh and they're back up. Once in awhile they last long enough for me to check the server status at my host where it confirms the server is down. But most times the problem is cleared up before I see the status.
Is this normal for a host? I'm never had the problems when working on other sites not at my host.
