...from migrating OOF from YaBB to SMF, 23rd Sep 2011. These are the software packages that ran/run OOF.
A year of amazing stability (bearing in mind how we run this site like a bunch of cowboys), and virtually no unexpected (or even expected) outages, except when I had to physically move the server, and the broadband upgrade at the same time.
A good job we didn't hang on for YaBB 3, as its still nowhere near ready for release

. That said, I still miss YaBB's clean, uncluttered appearance, and always feel at home when I stumble upon a YaBB powered site

But SMF has proved to be ultra stable and reliable for us. Its fast, and the search function actually works, so all in all its been, with hindsight, a good move.
Now that I've banged on about how good/reliable/fast OOF has been for the past year, I need an outage to fix a filesystem capacity issue, so expect an outage announcement soon
