Hurricane Electric is dropping packets at 30-50% in their core. Here's a current mtr into my network in FMT2 showing packet loss starting between DEN and LAX.

I've noticed a few other users reporting similar issues on twitter.

We're seeing the issue on their San Jose link.
It's very hit/miss as their PAO links seem just fine

Things look to be back to normal now.
I'll be ticketing HE for an RFO to find out what exactly broke.
