Nightly latency issues

[Galibier]

I found tonight the same issues, ran a WinMTR trace (think a Ping that goes continuously until you stop it manually). The main issue was not ping, that never went over an average of 50-60. The problem was double digit % of packet loss on the last 3 IP addresses after The final Level 3 node in Montreal. So imo, the issue is their CSP and perhaps Level 3. I had latency psikes of up to the mid 200's with averages in the 50s and 60s on the Level 3 nodes between me and SE. The problem is Level 3 is my last 4 hops. Then I get packet loss when I hit the CSP at Hyperion's portal. Not my problem or that of my ISP.
