Sorry about that bit of downtime, but the database server was just about to imploded itself again, much like last December.
You may notice the forums are a bit different looking....by product of the upgrade, so here we are on Invision Power Board 4.1.xx...
Additionally we're now running on new hardware, and on a 1GBit connection instead of the old 100Mbit connection, so hopefully things seem a bit faster.
If you find you are getting odd pages (like no formating) try doing a forced refresh of the page (Press CTRL+F5 together on your keyboard). This should force the page cache to refresh.
