Downcheck.com, isup.com, etc.
I won't call this a good guide since many people know about it. But it's alright.
yeah I normally use this quite often ping just refuses to work sometimes for me.
Decent tutorial there. It works, for sure. Pretty known, but thanks for posting.
isitup.com is also one.
Cool, I will be using this no doubt. I always wonder if it's "Just me."
