This morning, during routine maintenance, AMPRGW failed to reboot. We're looking into the failure now. No estimate on when it'll be back just yet. - Brian
Keep calm and do your thing ;) It’ll be up when it’s up.
Thanks for the notification though!

Did you raise a P1 ticket with the support desk? What time is the ITSM meeting and what's the bridge number?
:)

You are working in a to large corporation Mark.. Brings me back memories..
Now that I work in a union, we go directly to the meeting and we use webex ;-)

We've identified the problem that caused this morning's outage. It seems that when amprgw is rebooted, as it was this morning to apply a kernel security patch, the machine comes back up just fine, but the Ethernet switch it's plugged into crashes.
There's been a project to replace that switch with a 10 GbE switch (already on hand, I'm told) for some months; I'll see if maybe we can get a little higher priority on the installation now that we know the old one is a problem source.
May you live in interesting times.... - Brian

Hello Brian,
1. What is the exact current network configuration for Amprgw/NT?[1][2] 2. Which make/model of switch exhibiting the problem?
Cheers, -Paul
[1] Reviewing the diagram at:
https://www.caida.org/funding/stardust/stardust_proposal.xml#tth_sEc4.1
shows 'amprgw' ("Non-profit Router", on diagram) and 'seaport' ("Capture Server", on diagram) being optically paralleled from the same ethernet switch. Where an outage of the switch should affect both equally. (ie. is the diagram up-to-date?)
[2] Reviewing the UCSD/CAIDA Network Telescope bandwidth graphs at:
http://www.caida.org/data//realtime/telescope/?monitor=telescope_attack&...
does not appear to show an outage/interruption in the in-flow of packets being captured.
Hello, My apologies for the specialists and and experienced OM. I don't understand : - What's the connection between Amprgw, Caida and USCD/NT? - Where can I find information about the structure of Amprgw
