After 1 year, 8 weeks, and 5 days, our core router finally needed a reboot. Unfortunately, the config had been saved while memory was tight, wiping it out. It has been a long process getting it reloaded again but it's almost completely done now. Most people had their service restored after an hour.

An upgrade is in the works to double the memory in the router. It'll get a faster CPU at the same time.
