Are they not doing these during maintenance windows? Anytime we get a notice from Cogent, Level3, Att they are always during a maintenance window at least a week ahead of time.  We have yet to see any maintenance window notifications from Hurricane Electric.  Maybe our circuit has never had to have one in a few years. Or maybe they have so much redundancy it doesn’t matter and we never see the maintenance.

I know that some companies put these sorts of updates on hold during the holiday season but I was wondering if anyone has heard of any unannounced security flaws that only larger companies such as Cogent would be privy to?
