Two IP Addresses
Posted on March 26th, 2009 by Chris Coyier
We now have two servers powering Are My Sites Up. They are both located in Sausalito, California at Joyent Server Headquarters.
- 72.2.117.212
- 72.2.116.95
Either one of these servers might be performing your site checks, and is subject to change. So, for those of you doing filtering of our requests, you should filter by both IPs.

Sorry off topic, but was there some kind of newsletter sent, as it was in my junk and i accidentally deleted it?
Thanks
There was a very short newsletter sent earlier this week. It was just announcing to everyone the new three-tiers of Premium service.
Ok, thanks for the reply.
I probably don’t need it then as i read the blog post
Quick Q – will these checks appear on my google analytics account as visits?
Nope.
