[AusNOG] Broadcast Storm - IX NextDC S1

[Ryan van Klaveren]

Hey all,

Did anyone else experience any irregularities yesterday (22 Sept)
between 10:39am - 11:50am ? (I know that sounds a bit vague) - but this is
what we experienced during this window:

* Our nameservers failing to do resolution
* Sydney transit routers had BGP flaps to IX NSW peers
* Sydney ASR router generated 143 logs of: PUNT_INJECT-5-DROP_PUNT_CAUSE:
punt cause policer drop packet casue 7 (ARP request or response)

Spoke to IX, who said:
"Yep we did, yesterday another IX had an outage (I believe a broadcast
storm occurred) around the timestamps in your logs, a number of our members
that had remote ends also connected to the other IX were affected by that
outage and that is likely the reason for their session to flap towards us"


Just trying to see if anyone else experienced it, and better yet have any
more details as to what may have caused it?



Kind regards,
Ryan van Klaveren
