Cogent and Level(3) appear to be fully partitioned as of 5:50AM EST.
You heard it here first.

On a related note, I've got some Juniper boxes with P-TUNNELs, and
spare transit capacity to both (3) and Cogent.
If anybody in the community is suffering from a loss in business as a
result of this partitioning (for instance, VPNs between singly homed
sites off of Cogent and (3), poorly planned as that may be :-), feel
free to drop me a note off-list and I'd be happy to work out some
temporary accommodations.
