Our monitoring service, Pingdom, reported that some of our customers may have experienced some timeouts early last Friday morning.  This was due to Internap doing maintenance on the fiber circuits.

The timeouts reported by Pingdom are due to "routing reconvergence" that took place at the end of the maintenance.  It's like what would happen if somebody suddenly closed the freeway and routed traffic over another freeway. 

We never lost full connectivity and it appeared to be hit or miss regarding which sites Pingdom reported as down.
