It just worked for me with no issues -- I have Verizon FIOS. I did have a week a couple months ago when I think Verizon screwed up their DNS stuff as I had to use a proxy to get to it.

It's down from my home connection, but not work, ~10 miles away.

Other sites also seem to be affected—including, cruelly, downforeveryoneorjustme.com.

I have Comcast and I was connecting to MeFi just fine all day until about an hour ago. Now, I get nothing. I connect fine to everything else. Weird.

FWIW, I can connect to downforeveryoneorjustme.com and it says MeFi is up.

Here what I get from a ping...

Looks like a problem with Comcast.

Working fine for me on Comcast. For now, at any rate.

Don't worry, I fixed it.

Yup. Back for me, too. Weird.
