We don't know about any problems unless people take a minute and actually write us!
There has been no changes to the server or our setup for many months now and we keep an eye on things all day, everyday.
There was an action we were doing on this server that caused slowdowns every other week when we ran it, so we're moving that process over to another server. That's the only thing I can think of that could be causing issues.
Thanks for the information -- the more you can provide about time of day, what you were doing, and then what happened exactly -- the better. It can help us troubleshoot possible problems better and come up with possible solutions. Thank you!!
