When the server completely went down last fall (which happened when I was on a trip to Ukraine, I had to rebuild the server dialing in from a hotel in Lviv) they replaced the hard drive, in case that was the issue. The server has two hard drives - one for the OS, and one for the websites. I'm asking them to put in a third hard drive to handle the log files. I found on my other servers that providing a hard drive just for log file writing helped things go more smoothly.
