HE Routing Issue
| Posted by dmst, 04-10-2011, 05:35 PM |
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.
I'll update this as I learn more. |

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.

Yep, I was seeing packet loss in San Jose as well, but back to normal now. |

Move along.

It is back one of our clients hitting an HE route incoming from across the pacific here. Anyone else seeing it back to bad responses again? |

Today I received the following RFO:
At approximately 2:10pm (PDT) on Sunday, April 10th, an outward facing
interface on our Equinix San Jose router experienced an issue. The issue
manifested itself as intermittent packet loss. An engineer was alerted
and the router was reloaded to correct the condition.
We are continuing to explore possible causes.
