Fun with latency - something up or not?


[link to this post]
 
On looking at my TBB BQM data this morning I note that there was a sudden latency change at roughly 1am today, this seems to be that my PPP session is now terminating on a Zen Telehouse gateway in London rather than one in Manchester

http://www.thinkbroadband.com/ping/share/54ec5655d79...

I see that sometime around 9am the minimum and average latency has become very variable and much worse than normal (I have had stable average latency of 18ms or so for months).

It's possibly due to differences between the capacity of links from Telehouse vs those in Zen's main data centre, but is this normal or just down to Wimbledon etc?

Thoughts anyone, especially Zen staff...?

I was seeing latency issues going through losubs.subs.dsl4.th-lon.zen.net.uk, bouncing the PPP session I ended up on losubs.subs.dsl1.th-lon.zen.net.uk and things seem to be back to 'normal'.

Hiccups just after midnight and raised latency at breakfast time seems to be a fact of fibre for some. Same for me with resold TTB.

I normally connect to a Manchester gateway but im connected to London at present.

BQM graph is all over the place. Has anybody reported this to Zen?

I suspect it's related to this planned work coming up on the 3rd.

Good spot, I knew about the maintenance but not about the re-routing prior to it starting.

Things seem to have calmed down this morning, another PPP drop in the early hours and then much calmer latency peaks with a small further reduction in minimum latency.
