Sure. Make sure you have alternate plans for when Cogent gets into anoth=

And while you're at it, see if you can find out what *other* surprises th=

(Yes, there's corner cases where =22single homing to a Tier-1=22 makes bu=

by a routing/peering spat. I don't think =22VOIP carrier=22 is one of tho=
