In this case, it would probably have "helped" in the same way as
rebooting or waving a rubber chicken or whatever sometimes "helps": the
route issue was caused initially by a problem at Verizon that
caused them to deaggregate, which they fixed, so by the time someone had
identified the problem, paged someone, gotten them to the data center,
had a teleconference, rebooted the device, waited for it to come back
up...  Verizon would have fixed it, so when it came back up it'd be
back under 512k again.
