I'm seeing high packet loss in the path NYC <-> EU now and it has been coming and going for a while (a week?).
As seen from the NYC side:

So the problem shows a bit assymetrically, but there's a lot of packet loss no matter how you look at it.
Anything going on?
An optic on one of the 10G circuits between New York and London failed this morning, the wavelength involved was moved to a different port and brought back up.
Everything should be fully operational now.
We have many US, translatlantic, and European circuits pending delivery that will nicely improve the network in the next few weeks.
Heh gotta love HE. Response from the CEO!

Ok, thanks for clarifying what's up!
