"According to NANOG, and complaints tracker DownDetector, many Internet
providers — including Comcast, Level3, AT&T, Cogent, Sprint, Verizon, and
others — have suffered from serious performance problems at various times
on Tuesday.”

While we had a few multi-homed customers have problems with their routers,
we did not see anything in the core.  Is this just a ZDNET reporting error?

I note that the recommended command in that article, "mls cef
maximum-routes ip 1000", will throw most of your IPv6 routes out of
the TCAM instead. Which if you have any IPv6 traffic of substance just
kills you in the other direction. Might want to try something more
like "mls cef maximum-routes ip 900".
