Up until now, I’ve been running Debian Lenny on this server. Lenny is now being retired, so I’ve upgraded it to Debian Squeeze. This also means that Apache, PHP, MySQL and other packages are all running on newer versions than before. I think the site should be a little faster now, as a result.
There may, however, be some funkiness, with things not working as expected. This is the first time I’ve upgraded Linux on a box that I haven’t had physical access to, and the first with a complex hosting setup, so something is likely to have broken somewhere. That being said, so far everything seems fine.
