Dear all, I hope you are all well, Covid-free, and perhaps back in your offices (either the classic one or the home variant) and "behind the wheel" again. Me, Olav and Olaf at Uninett have started preparing a new variant of our proposal for a Nordic collaboration project on end-to-end monitoring. We aim to have a first draft of our document ready by tomorrow. We would very much like to have feedback, hence is doable for you to read through those few pages and join a quick online meeting on Thursday Aug 26th to give us your comments? Calendar invitation with Zoom-link is incoming in separate email. BR O2 -- Otto J Wittner tel +47 99550566 Uninett AS http://uninett.no

what microdep can help with : -------- Forwarded Message -------- Subject: outage amazon us to trondheim Date: Thu, 12 Aug 2021 15:01:42 +0200 From: Olav Kvittem <olav.kvittem(a)uninett.no> To: stamnett(a)uninett.no <stamnett(a)uninett.no>, NORDUnet NOC <noc(a)nordu.net> Hi, On 2021-08-10 we saw outages from Amazon US est to Trondheim. 3 outages each close to 20 minutes between 14 and 15 oclock and a few smaller ones indicating a turbulent network situation. (coloumn 2 is seconds outage)) Traceroute visualization shows red nodes where the route has stopped. We see several nordunet routers in the list which indicates routing instability. See https://iou2.uninett.no/microdep/tracetree.html?topo=/dragonlab/mp/amazonuw… if access control permits. The other way we also see routing turbulence even within uninett ( oslo-gw1 and dk-bal2 has lost amazon prefix). We propose project to develop alarms based on traceroutes when main routes fails like this. Olav
