Here's an example of the increase, while the ADSL was still connected.
2 13 ms 14 ms 13 ms losubs.subs.dsl1.mbr-roch.zen.net.uk [126.96.36.199]
2 27 ms 27 ms 29 ms losubs.subs.dsl1.mbr-roch.zen.net.uk [188.8.131.52]
This isn't the first time this has happened but it doesn't seem to be resolving itself as it did in past cases.
Here's another oddity. The pings decreased in ~10ms increments until back to normal. The first drop was caused by a reconnection to get a better gateway, although the original gateway started off at the >50ms mark and dropped down over a period of a few minutes until it hit the ~20ms mark, all without any reconnection. It seemed a little bit like (alright, exactly like) the connection profile was set on auto interleave and a burst of errors has caused it to increase the depth, although I've been told that it's not. It happened a bit too quickly to be clearly seen on the chart.
As a gamer, I value a connection with low latency and given that I use fast path, I value it over speed. However, the latency I'm receiving at the moment is worse than I'd expect to receive on your average interleaved connection.
So, my question is, has anybody else experienced similar oddities or have any possible explanation of what's going on? I really can't think of anything apart from the connection possibly being mistakenly on auto as I believe it may have been prior to my move to Zen (it'd explain a lot as the same behaviour is visible in my last ISP's monitor). I've seen the behavior of the system when a line has a burst of errors after moving to Zen when the line was set 'back' to auto. Doing anything intensive with the connection at that point triggered a ~10ms hike in latency.
Finally, it may sound like a conspiracy theory (it's not ) but this sort of thing seems to always happen at around 10am. I can produce a number of monitor graphs showing drastic shifts in latency at around 10am. Complete coincidence? Maybe, maybe not.
Sorry for the slightly incoherent post and thanks!
