Looks like maybe Sprint and Cogent are experiencing communications
difficulties in the DC (and probably other) areas. Theories include
a potential depeering.

Not a theory.

I am seeing issues Cogent -> Sprint at Tyco Road, Tysons Corner VA.

All my traffic to Sprint is not being trasported over Cogent backbone here in Central Europe.

Indeed. It appears, using Sprint's looking glass, that they're completely
partitioned from Cogent. YMMV.

I wonder if judicious use of 6to4 and Teredo would allow an IPv6 (single homed) user to access now missing parts of the Internet. Me thinks, yes.

Last I knew Cogent wasn't doing any IPv6.. has that changed?

Not that I know of. We tried to get IPv6 transit from Cogent several months
ago (we already have IPv4 transit), and were told it's not available yet.

What a shame. It's extremely miserable, but Sprint has a 6to4 at least. No clue what they have beyond that. It's been a big motivator for us peering native IPv6 so we can push our customers away from that death trap. Yeah, we can tunnel, but most tunnel peers seem low band.

The most interesting part of the press release to me is:
In the over 1300 on-net locations worldwide where Cogent provides service,
Cogent is offering every Sprint-Nextel wireline customer that is unable to
connect to Cogent's customers a free 100 megabit per second connection to the
Internet for as long as Sprint continues to keep this partitioning of the
Internet in place. Unfortunately, there is no way that Cogent can do the same
for the wireless customers of Sprint-Nextel.

This wasn't the first time Cogent offered something similar. They did the
same thing when Level3 depeered them.

Did they provide you with a roadmap ?
