BlueHost, HostGator and HostMonster down

It appears to be a network issue that is affecting all of them, I would therefore assume that it's an issue on their upstream transit providers, or if they share a data centre then it could be a localised network/power issue.

I'm using HostGator on 1 of my sites, and can confirm it's NOT down. Are you sure it's just you?

It's hard to say, but I just did a write up about what we saw in our data: http://reviewsignal.com/blog/2013/08/03/service-interrupted-...

tl;dr: companies have outages, big ones seem to regress to the mean. There are companies that are liked a lot more though.

Definitely down: http://mashable.com/2013/08/02/bluehost-down/

First: what the heck is going on & how is this possible? Second: Note - THEIR sites are not down. So who the heck is THEIR server? ; )

Yes. Move to a VPS provider that has never been down.

JustHost was down as well. It came back online now.
