Who in COLT did you email? Nothing came in via [email protected]
regarding this.

We saw this route from a peer that was announcing us a huge number
of routes that for some reason max-prefix didn't prevent from happening,
although after rebooting, the box did take the session down. My guess
is that the routes announced to us had sometype of corruption that
didn't send it through the max-prefix subroutine properly to detect
the number of routes being advertised.
