Anyone else experience sporadic funkiness via Level3? I can't even reach
the main website from who knows how many networks I've tried. Also
friends and former colleagues have tried to reach the site to no avail.

One of my machines on AT&T:

Confirmed it can't be reached from Travelers Ins, The Hartford, none of
my connections. Anyone else seeing issues? I'm seeing drop off from
clients going through their Atlanta interconnects with Charter and two
other providers, which I can't make sense of. I DO KNOW they experienced
some sort of issue with a TDM switch or so they said... Very broad
statements: "We know teh interwebs are down please stand by"

I know websites are one thing, but the chances of the website going
down, a TDM switch being wacky and now clients traversing their networks
complaining all at once seems a little out of the ordinary.
