TSI/HE.net performance/packet loss issue

I've started to notice some slight packet loss tonight and it seems to be between HE.net and TSI in Toronto or at the Ottawa POI, he's an MTR from both sides:

Routers are generally set to have pings as the lowest priority, so seeing packetloss on a traceroute doesn't mean too much. If you ping google.ca and let it run for ~200 packets do you get any loss?

true, however you'll notice packet loss happening at the end points and so the conclusion can be made that there is an issue in between and both routes show its happening somewhere inside TSI.

that combined with slow speeds and other reports tonight indicates there is/was a problem, however I don't see TSI responding to this issue.

Yes, which is why I suggested Google. TekSavvy peers with them through Torix, so it would separate TekSavvy's network from HE's network (or any other transit provider). I don't see any pings to non-router destination's inside TekSavvy's network, and I know I frequently get packetloss when pinging TekSavvy routers (even when I've got zero loss to the end destination). If you saw packetloss from Google too that would suggest something wrong inside TekSavvy's network, if not it could be an HE issue. Both HE and Google appear to connect through Torix, so you'd be going through the same TekSavvy equipment.

I'm not seeing any packetloss from Google, and as we're both on cable we go through the same TSI equipment (different POIs connect through a shared Rogers connection). It could be a Rogers issue with your POI, which isn't TSI's or HE's network.

the packet loss is occurring at the St-Laurent POI level. We've had an upgrade order on there for a while now and it's getting installed on December 11th (next week)

Will the upgrade be seamless or can we expect an outage?

As per past POI upgrades, no service interruptions occurred.

Thanks Martin - I guess I will be working from home that day after all.

Now for my uninformed self, when we're talking POI upgrades (since I never concerned myself with this in the past) are we talking new hardware to increase capacity, or hardware redundancy, or something totally different?

It's to increase capacity.

curious but what does St-Laurent currently have for capacity and what upgrade is happening, a single Gig-e?

It's probably to go from 3 to 4 Gig-E. Although I don't have specifics, our upgrade requests have always been for Gig-E.
