We had some problems with our web server tonight. The power supply was on its way to completely failing, causing the server to reboot itself several times. This affected the main website, the forums, our IPv6 site, and the newspipe.
Since the old chassis was a custom 1U PIII 700, rather than replacing the hard to find 1U power supply we transplanted the hard drives to an extra Sempron 2500+ in a 4U case we had in storage. In addition to fixing the power supply problem, the forums and newspipe should be a bit faster than before.
