If Roughbeast and Maverick go through the same Core equipment, and if that is congested for other routing reasons, then minimum latency would rise.

Igni's written about that somewhere, I recall.

yes core network congestion would cause that also but isnt the core network supposedbly in good shape :p

It isn't the core network. It's a few edge nodes. It's been showing up in Scotland since at least Feb 26th.

Both Roughbeast and Maverick's base latency makes it look like they're up north somewhere, in fact pretty much as far north as VM's network goes. Even though RB's profile says he's in Coventry.

... That or they got routing problems.

Ehm... When was Sky Anytime+ made available to VM customers again?

I'm in Cheltenham, pretty much the polar opposite :D

Definitely Coventry. It all gets routed through Birmingham after that.

Of course, it could all be that TBB glitched as happened a few weeks ago.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 
It's not a TBB glitch as it's been happening several days a week for over a month, and only affects certain nodes even along the same route (say Edinburgh CMTS 13 but not CMTS 14)

VM seem to have some very slow routes for some reason. Edinburgh to Manchester is a ~250 mile path, and takes only 5ms. Birmingham to London is about 100 miles but taking 8ms for you. Manchester to London, which is about twice as far, only takes 6-7ms for me.

(Incidentally VM also have a very slow route to Amsterdam)

Despite having over four times as far for my data to go, it only takes 15% longer (18ms) to reach London from Edinburgh than it does for you. My TBB monitor actually has the same minimum ping as yours, despite being 4 times further away as well, which is really odd.

Not sure of the infrastructure implications, but from Staverton pinging a Manchester based server, it goes Staverton -> Aztec West -> Guildford -> Birmingham -> Manchester (TC). Which from a geographical persepctive makes no sense at all, and if you view the VM business infrastructure map there is a direct link from Staverton to Birmingham.

:confused:

tracert to pingbox1.thinkbroadband.com before and during the 'hump'??

where are these maps?

MaverickJesus 21-03-2012 21:31

Re: Think Broadband Ping Monitor Results (POST YOURS)
 
It was a little Flash tool someone posted in one of the other threads on here a while back. Showed infrastructure paths, fibre access areas, a few other bits and pieces - you could flick through different views of the UK showing different things.

Can't find the link off the top of my head, if I find it i'll post it.

Yeah I was seeing London => Birmingham traffic going via Manchester as well, but only in one direction.

My evening bump was much smaller yesterday. Why would Wednesday be any different than Tuesday? PC usage was the same.
