I get packetloss on te-1-12-0-0-ar01.sfsutro.ca.sfba.comcast.net to my linode @ fmt at weekends and at nights, looks more like just too much load rather than an outage
In my case, all packet loss seem to be within gblx.net (e.g. no packet loss between Comcast and hetzner.de).
What I find strange is that the latency is still very good, even when there is a significant packet loss.
But my ssh connection between Comcast and Linode/Fremont is completely unusable for several seconds at a time during these events.
The loss seems to have continued throughout last night:
