I'm experiencing this in the southeast US region. Unfortunately, return traffic from a data center that we have a VPN connection to. Is routed first over Level 3 who is then handing it off to Arelion in Miami where we then see the 200 to 300 millisecond latency and 50% plus packet loss. On Tue, Oct 24, 2023, 11:22 Elmar K.

We also observed this today, UTC morning, esp. across the pond, and our alternative paths from Europe to the US were suffering from the still unfixed fibre cut, so I was a bit unhappy with 200 extra ms, and 60% loss.
1299 seems to've found an alternative path in the meantime, looks good to us.

We had the same issue with Arelion this morning, a huge increase in the latency and jitter was happening across the US and of course for any traffic sourced from the EU flowing to the US. Within the US we noticed a latency spike from 20-50ms to ~200ms. From the EU to our US facilities, we noticed a spike from ~130ms to ~400ms.
We ended up shifting traffic from Arelion to a different carrier, and will stay there until we are confident that they fixed any issue that they had in their network. To be honest, we've been experiencing quite similar issues with unstable latency on Arelion over the past couple of months, and it's becoming quite frustrating

Hey all, anyone aware of issues with Arelion this morning? We have a bunch of end users on at least Cox and Cogeco who are having serious issues with service access, and the problem appears to be on the return path where it traverses Arelion. Source net is Lumen/L3 3356 but loss/latency doesn’t appear to creep up until already within Arelion’s network.
Imperva mentioned outage/degradation due to a national ISP issue too, so I suspect it’s affecting more than just certain peerings.
Thanks,
David
