[outages] [Fwd: Re: Undersea cable cut?]

[Chris McDonald]

i'm not sure one necessarily fails to the other... if people don't subscribe

transrussia overland routes, they're out of luck.

i frankly don't believe enough capacity exists on the transrussia cables to
backup swm3 and swm4.

i work for a network based across the pond
