yeah they do, have done for nearly 2 months now

They sort of do. My area was one of those "being planned" places that got a date in may iirc with the last update.

At the same time as the early speed uplifts began they announced that they had completed the work to enable 100meg everywhere. But at the same time, they were only uplifting people in areas ready for it and even then only to 100/5. So basically anyone here will be on 100/5 if they managed to wrangle an early uplift which I doubt. 150 say they can't move me to the real 100/10 product, nor can they early upgrade me to 100/5. Same with the website.

Ah. In that case, same here then. Hence the half of 100mb service I mentioned.

Thanks guys at your previous post up suggesting me to change for a 6db profile

i will keep the interleaved for now as is very stable connection even i know can get lower ping and maybe more speed(11-12 mb right now any time of the day or night)
beside i have the VM for fast internet

so here the Talk Talk adsl line with interleaved snr 12 (currently in use & bear in mind is direct to exchange & not via cabinet)
wonder why every 15 minutes are spikes like comb when connection is idle(only can think is because 2 pings going to same router so i may disable the VM monitor or connection and see how it does in few days)
also seems line it does not affect at peak times like VM

both from the same router all in one vigor 2850n

VM 100/5 not been in use atoll, yesterday's graff

Can someone please remind me what causes the change in minimum latency? AFAIK VM don't mess with the interleave.

Routing.

Interesting to see VM's backup route is twice as fast as their normal one...

Good point, qasi.

Look at this

Yearly Graph, that's the reason for the ping increase, might just leave.

Mine kinda mirrors sephs this morning, though the drop in latency is not quite so much, there is a step down like it took a different routing for a couple of hours. after noticeable packet loss. Wonder if they were working on something.

yep although probably not the cheapest ;)

VM is a bulk transfer ISP.

Yearly graph ping increase is irrelevant.

Every CMTS increased at the same time because they moved the server doing the pings to Germany.

Yeah, that's my suspicion. Hub-and-spoke is still one of the most economical options, even if the spokes sometimes go the wrong way. Likely the packet loss was a link failure or maintenance and traffic automatically re-routed to a lower latency, but perhaps lower capacity path.

BT has been doing maintenance lately too which has been causing similar effects (though in their case ping goes up, not down, because they're already using the quickest path by default):

Personally I can deal with base latency going up a few ms as long as it doesnt get stupidly high. I think a bigger impact is jitter, so if base latency is 20ms but stable thats better than a base latency of 15ms but all over the place. On interleaved adsl lines it can get too high especially on BT wholesale because from here it goes to birmingham than to london.

On ukonline(easynet) I had a base latency of 8-9ms to the bbc with non existant jitter. They have a POP in my city which goes direct route to london.
BTw is about 17-25ms on fastpath depending how BT route it and about 35+ms on interleaving.
VM is about 14ms base but obviously varies with the jitter.

That's why I moved to BT, base is 19ms and average is 19ms, whereas VM had a base of 15ms and an average of 20-30 for most of the day.

Course as you say, it's as much dependant on routing with both ISPs, in my case both VM and BT go Edinburgh => Manchester => London with no roundabout paths, as BT and VM both have core nodes/BRAS' right here so it's about as good as it gets for both. Neither VM or BT have any core nodes north of Edinburgh or Glasgow though.

My VM used to be 14ms base, until routing sent me around the country...
Now it's 20-21m + jitter ~5. means i can have 26-27ms nearing interleaving standard.
