I'm tempted to say that forwarding it is even worse than originating it,
because it proves they weren't sanity checking what somebody else gave them...

tl;dr: Massive DDoS.  Usual affair.  Welcome to the Internet.


Anyone know how big really?  One org's "Massive DDoS" is another's "oh, is 
someone sending us some extra DNS traffic again?"

As a Cogent customer, I say ‘good luck’

Last time I called them on a Friday night, it was because they announcing (not 
originating but bad nevertheless) the IPv6 default route. The NOC “engineer” I 
spoke with adamantly insisted that there was nothing wrong with this. After 
about a half hour I gave up. The next morning, another tech, wanted an error 
message or a route as an example. It wasn’t until Monday morning that they 
blocked the route.

All I know is that when our contract is up, I can assure you, we won’t make the 
same mistake twice.

I was getting 20% TCP packet loss between two of my unix boxes on the
TWC route from my house to work, so I called support.

I used lft - like tcptraceroute - both directions, to identify a TWC
backbone router in Dallas as the problem. I then used the TWC looking
glass to show the same result.

I was told i needed to reboot my router to troubleshoot. I offered to
reboot my router, after he rebooted his router in Dallas  ;)


Conversation with one of my daughters earlier about a problem in her 
office today (short summary as I recall it):  Changes made to their VOIP 
system the night before,  stuff broken the next day.


She tried to get "support" to look at the changes made, "support" would 
not do anything until she had rebooted everything including the 
microwave, I guess.


Back in the day--my main trouble shooting strategy was to identify all 
the things that had changed since it last worked the way it was supposed 
to.  The big trouble with that approach is that everybody and their pet 
spider will decide which changes are "important".
