I don't really think this is throttling related, but i'll put it here anyway.

Just about every day I get the "rubber banding" lag starting at about 2pm ET.

I did a tracert this morning before the lag had started. The whole route is sub 30ms until the last 4 hops, which were:

11 34 ms 35 ms 36 ms 66.198.96.50
12 65 ms 71 ms 65 ms 192.34.76.2
13 71 ms 71 ms 71 ms 199.91.189.234
14 54 ms 55 ms 54 ms 199.91.189.42

Now that we're in lag territory, I've been running more traces and here's what i'm getting on those hops:

11 * 90 ms 92 ms 66.198.96.50
12 99 ms 101 ms * 192.34.76.2
13 97 ms 98 ms 96 ms 199.91.189.234
14 101 ms * 96 ms 199.91.189.42

Those pings aren't terrible, cept the timeouts XD, but it definitely shows a difference from before.

This post is FWIW. My ISP here is Level 3
