That’s quite ironic, I was in SY1 last night thinking it’s been a while since Megaport last had an issue with a storm on the IX, maybe it’s time to bring up there peering VLAN again, we turned it off about 2 years ago.

Clearly I was wrong, Murphy’s law!

Hi All,

Did anyone else observe a storm on MegaIX Sydney this morning? At approx 9:40am ACDT, I saw log entries for " punt cause policer drop packet casue 7" on the router, and moments later the switchport dropped into err-disable for storm-control (currently set to "level 1.00" on a 1Ge port).

Unfortunately I don't have much in the way of analytics to identify what it actually was, or the source.
