HE is having issues in Europe. I spoke with them an hour ago, they said they were aware of the issue but didn't have an ETA. Based on the traces we saw issues with connections coming into London.

Hello,
We are currently experiencing massive packet loss from Amazon EU-West 1.
This page http://ec2-reachability.amazonaws.com/ will show most of
eu-west-1 as down but actually it is packet loss of 90+ %.
I have found that if I shutdown our link to Hurricane Electric the
problem disappears. Also it is only an IPv4 problem as IPv6 is fine
(also going through Hurricane Electric).
A traceroute shows everything ok until the first hop inside the Amazon
network. The peering is apparently at AMS-IX.
Right now we are ok because I am keeping the HE.Net connection down, but
I managed to find another NLNOG Ring node that has the same problem:
gigabit at casablanca01:~$ ping 52.16.0.2
PING 52.16.0.2 (52.16.0.2) 56(84) bytes of data.

rtt min/avg/max/mdev = 35.170/35.220/35.251/0.232 ms
That IP is one from eu-west-1 taken from the ec2-reachability page. When
I ping it with the HE.Net link down there is 0% packet loss. With it up
we are seeing something like the above. However I notice that Casablanca
is going out through Telia not HE. The return path could very well be
via HE of course, there is no way to know that.
