| 25% Packet-loss Starting at Toronto For the past couple of months maybe longer, I've been seeing a lot of packet-loss between 10PM - 1AM EST, it seems to start at Toronto, but I'm guessing that the problem is before the router somewhere between Nova Scotia and Toronto. I've contacted my ISP (Seaside Communications) a few times and they've done nothing, not even a follow-up phone call to let me know there's nothing they can do about it or who to contact.
I'm just wondering if anyone else is seeing an issue like this and what can I do about it? Also looking for suggestions on what else I can do to narrow down the problem. Ping is great for troubleshooting connectivity and giving an idea of potential problems like this, but it's not absolute and even fancy tracert programs like Pingplotter lack the necessary detail for properly troubleshooting this.
Downloading is fine, torrents are fine, youtube works great streaming 1080p, but VoIP and gaming is impossible during those hours mentioned above.
Here's a couple of screenshots in an Imgur album highlighting the issue. For anyone not familiar with Pingplotter, ignore the graph at the top and instead look at the time-line below. Red lines show PL, black lines are latency, scaled 0-150ms. Timeout is 3s, packet send delay is 40ms, packet size is 56B, and the trace interval is 1s.

The first four screenshots are 10 minutes in scale, second-last screenshot shows the problem over a 6 hour period, the last one shows what it normally looks like, although the scale is only 5 minutes.
Some more info, probably not needed as I don't see any issues on the ISPs LAN:
Cable 10/1mbits
SURFboard SB5100 v2.3.2.5-SCM01-NOSH
Down SnR: 37 dB
Down Pwr Lvl: 3 dBmV
Up Pwr Lvl: 36 dBmV
Any help would be greatly appreciated, thanks. |

kudos:1 | Looks like typical TATA congestion (upstream provider from the ISP). It's seen every so often with them coming out of Toronto. I could be wrong but have seen that before with them... |

You have a D2 Cable Modem by the looks of it.. D3's fix a lot of node congestion. Toronto has too many people to not be using D3 modems. I would recommend you upgrade your modem if possible. I have a strong feeling it's local node issues, that D2's are unable to get past. |

Yeah but he's not in Toronto - he's in Nova Scotia where Seaside is based  |

I get confused easily, do you mean the problem could likely be TATA, or my ISP? Would using their looking glass provide some insight? They have a couple in Toronto, Montreal and one in Scarborough, not sure what one to choose. I'll play around with them next time the problem occurs.

Could this be some kind of peering issue--my data is getting side-lined for their customers priority traffic?
Sorry if that sounds stupid I haven't taken any courses in networking (obviously haha), just google and wikipedia. Thanks for replying. |

kudos:1 | Best guess is that TATA itself (your providers upstream) is having some congestion issues - have see that with them out of Toronto before... only an educated guess |
