Hurricane Electric packet loss

Tue Jul 22 10:49:55 UTC 2014

Hi,

Yes - I am not posting cause of a bad looking trace route. ;) We are continuously monitoring our systems from locations around the globe and we see actually packet loss across services - HTTP, etc.

I have had a bunch of off-list replies that indicate that others are seeing the same issues. So we are not alone with this.

Cheers,
Wolfgang

We?$,1ryve been customers of Hurricane Electric for a number of years now and always been happy with their service.
In recent months packet loss on some of their major routes has become a very common (every few days) occurrence. Without knowledge of their network I am unsure what?$,1rys the cause of it but we?$,1ryve seen it on the Tokyo - US routes as well as the London - US routes. It reminds me of the Cogent expansion which was carried out by unsustainable oversubscription which eventually resulted in unusable service for a number of years. Having seen some of the rates that HE has been selling for I can?$,1ryt help but wonder if they made the same mistake ...
Here is an example of what?$,1rys going on again atm.

Is anybody else observing this as well?

Why do you think this indicates a problem? Are you seeing *end to end*
packet loss?

And have you read this Nanog presentation?
