I think it crashed

[TWIN Mark]

I have no idea what happened. I was about to reply to my friend's post on my forum (which I love the service ty for it), suddenly I got redirected to a page saying "Oops". I copied the error message below.

Is there anything I can do, or is it like a fluke?

[Will <Nabble>]

Yes, the server was restarted. Now it's back to normal. Thanks for reporting the error.

[Tom Mcgreevy]

Been having a few probs with different servers this week myself. At approx 1.00am this morning ( English time ), all 3 computers in our house went dead. No internet available. Error messages were saying ' Problem with DNS Server at ' Microsoft.com ' This morning all was back to normal and working fine.
