Back now. Yay.
Thanks for sticking with us whilst we fiddled with our server hardware. Apologies for the 12-hour downtime - it was, unfortunately, necessary to diagnose some issues we've been having with our boxes!
However,
bit-tech is now up and running, and normal service is resumed. We don't anticipate any more downtime in the near future, so rest assured that all's well that ends well.
