Ah well. It lasted the entire 90 minutes at least and it going down for a brief moment isn't too bad when we've basically just had 100 people logging onto the forum at once.
Considering the state the forum software is STILL in (we're still sorting out some absolutely major stuff that it's missing, basically, which should improve things no end) I'm personally amazed it's done as well as it has since the move.
The problems we've been having aren't server related, they're to do with our forum lacking a lot of what a forum of this size needs (namely an optimizer/accelerator that can improve performance by 80%, having all our images hosted off-site which also supposedly makes a huge difference and the fact that our database isn't fully tweaked yet to work with the forum).
The hosts are installing all of that stuff for us as we speak though and they should be in soon. I'd expect SMF errors to be banished with all of that happening.
I know it sounds crazy, but we are actually one of the biggest SMF forums on the internet - especially when you consider how many posts we've deleted from here over the years (our archive only goes back to January 1st 2007 now).
The biggest SMF forum (redandwhitekop) has 6 million messages over almost 6 years of running, we have around 1.2 million in less than 2 years, so imagine how close we'd be to that size if we'd kept everything since 2005.
Just to give people an idea of the scale we're working with here.
