No problem :) I imagine it's probably an issue that will clear itself up.
If you want to see where the bottleneck is, you could try doing a traceroute on command prompt. Enter command prompt on windows, and type:
tracert scirra.com
It should come up with a list of all the routers along the way to scirra.com and their response times.
I expect you will see at least one which is very slow!
