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.  
FWIW I have a few Cogent circuits, The maintenance look normalish and
are all scheduled per their normal process, I aware of at least one
cisco bug related to source mac usage they had that was annoying if not
catastrophic since it was visible on our ports.

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?
