Looks like maybe Sprint and Cogent are experiencing communications difficulties in the DC (and probably other) areas. Theories include a potential depeering.
I am seeing issues Cogent -> Sprint at Tyco Road, Tysons Corner VA. .......... ....... ..
show ip bgp 206.159.101.241 % Network not in table

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