      About as ugly as a graph as ive seen!  Reverse path for this site is cogent, mtr and forward ISP failing me a bit not returning the transition hop IP I need to verify, but im assuming its Arelion.  This site is in the southeast also.

We also observed this today, UTC morning, esp. across the pond, and our

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

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.
