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.  
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.

Hello,

Over the last several days we have had interruptions at multiple times in our service with Cogent due to them 
performing router code updates on multiple nodes. 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?

I am certain that if you have heard of these flaws you cannot post the details but a simple yes or no about the 
existence of such a thing is plenty for me.

Happy Holidays

Thanks,
-Drew
