Yeah I forgot the exact time. I actually barely slept at all last night but I had a PC repair job this morning. Came back from that and spent most of the day sleeping while my miners purred in the background.
http://i0.digbtc.net/ for me seems to bring up a blank page. http://www.digbtc.net/ does seem to take a long time to respond but did come up eventually.
io.digbtc.net comes up almost instantly for me, despite close to 300ms ping. On the other hand www.digbtc.net takes a while to respond despite the server pinging under 200ms.
You might want to traceroute the pools and see which is actually better for you. It might be how your ISP routes to the pool that's causing your mining efficiency to drop even further.
