Update: And we just got this from Sprint --
Let's hope those glorious EVOs resume normal operation shortly."One of our VoIP switches in New York did experience an equipment failure earlier today causing some traffic to be rerouted to another switching location during the repair process and resulting in call congestion for some Sprint customers. Our network operators are working aggressively to resolve this issue and hope to have service back to normal soon."
Update 2: Looks like we're back online, at least intermittently.
Update 3: Sprint tells us that service was 100 percent back to normal as of 4:15PM ET. Carry on, folks!
