Not sure if its just me or not but sometimes there will be 15 or 20 minutes where the site just wont load or loads very slow.

really? I haven't noticed that myself, where are you located?

East coast. It's almost always around 10 to 11am when the site slowdown occurs.

I assume you mean 10-11 GT. Do you notice other websites doing the same? Like youtube for example. If so, it could be your provider slowing it down :/

same here the last few days (UK)

Well, I just moved a data-logger off the server, so maybe it'll be better now?
