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.

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
