My hunch is that this is fallout and repairs from Juniper PR839412. Only fix is an upgrade. Not sure why they're not able to do a hitless upgrade though; that's unfortunate. Specially-crafted TCP packets that can get past RE/loopback filters can crash the box. --j On Tue, Feb 5, 2013 at 7:39 AM, Josh Reynolds <esseph@gmail.com> wrote:
I know a lot of you are out of the office right now, but does anybody have any info on what happened with L3 this morning? They went into a 5 hour maintenance window with expected downtime of about 30 minutes while they upgraded something like *40* of their "core routers" (their words), but also did this during some fiber work and completely cut off several of their east coast peers for the entirety of the 5 hour window.
If anybody has any more info on this, on a NOC contact for them on the East Coast for future issues, you can hit me off off-list if you don't feel comfortable replying with that info here.
Thanks, and I hope hope you guys are enjoying Orlando.
