We've procured a new eqiad-esams wave. This task will track its implementation.
The esams side is apparently ready, we're waiting for the LOA; the eqiad side is being actively worked on.
Commit date is the 26th, firm date is the 22nd, optimistic delivery is on the 18th.
This took a while, with a lot of back and forths with Level3. They finally managed to patch their equipment in Ashburn on Aug 12th and in the Netherlands in Aug 13th (yesterday).
Latency is ~84ms, approximately 1.5ms more than our GTT link. I configured PIM, OSPF and OSPF3 (all with BFD) yesterday and ran a 10 minute test, after which I informed Level3 of the successful status of the link. The link has remained stable ever since and as such today I increased the metric on our other link to 1820 (820 because it's a ~82ms link + 1000 on virtue of not being a dedicated wave and thus downprefed).
I'll be closely monitoring it for the next few days. With the other link being still active and with both of them having BFD enabled, this is actually a pretty safe move (and is actually less risky than waiting to configure it).
