Slow speed after GEA migration

In reply to a post by SteveBushell999:

The second line is now up and running as about midday yesterday.

I assume that the new line is on BTW and my original one is on BTW as well for now?

It’s early days, but……

I was getting solid 500Mbps from the old line, the new one was installed, and I tested it at 500Mbps as well…

Now the rather more worrying news. After an hour or two the original line dropped back to 100Mbps, and then similarly the new one.

I swapped around the ONT connections so I am now on the ‘new’ line, and it was fine (500Mbps), before dropping back to 100Mbps after a while.

I powered down both ONT’s, and then got a full 500Mbps on both lines, followed by the new line dropping back to 100Mbps after a few hours.

I have since powered off and on the new ONT, and have 500Mbps back on both connections.

I am monitoring the situation, but it ‘seems’ that both of the lines may now be unstable???

I know that the new line apparently went back to an 8 port Huawei box at the end of my cul-de-sac (if that is any help) – no idea where the existing line egresses.

Update, both running OK as at 22:50 Thursday. I updated Zen this afternoon, but both Brandon and Andy are on vacation....

In essence, it 'feels' like there is something really flakey here, but time will tell, perhaps it's all just retraining or whatever....

Could it have been the Ethernet connection to the ONT dropping down from 1G to 100Meg randomly for some reason?

ANYTHING is possible, can't say I checked much as the first day it was all installed I was out much of the day (my birthday), but somehow it all stabilised, and we seem good now. Zen have sent out a SamKnows box for them to monitor the original (now GEA) line, that box arrives tomorrow. For now, both lines currently behaving well, but I have seen all sorts of issues in the last nearly 5 months, so anything is possible.

This 'incredibly long thread' has been going on an 'incredibly long time' - We have ALL tried very hard to keep all interested parties informed as the situation unfolds, and I suspect that the origami is very far from over. I note that poster isn't even on Zen! Hopefully they find these shenanigans of passing amusement.....For 'us' though, it's been of very real, and impactful interest. Guess you can't please all of the people all of the time

For my part, I am finding it quite interesting that my original line re-migrated seems much better than it was back in June before I got switched back to BTW, wondering if either something else has changed, or simply disturbing the connection physically has done something? Time will tell..... (or not!)

I pruned one of the August sub-threads.. you can quote from the original thread in the new one irrespective of where it was split.

I don't think there should have been any real physical disturbance to the connection. You'll be on a different CBT port for the new connection. I'm not actually sure they physically move anything at the exchange when you move between GEA and BTW backhaul (certainly nothing at the fibre PON end will have moved).

It's a shame in a way that you moved off GEA originally It's possible now that perhaps it was a difference in the provision process somehow, or that they've made in the intervening time changes to the GEA setup at your exchange or elsewhere that would have fixed your original link at some point in the intervening period had you been still connected to it. Maybe they've swapped out some exchange hardware, who knows. (They've tried swapping out a bunch of SFPs at my exchange it seems in recent days).

So are you running both connections all the time, or just swapping the ethernet cable between ONTs to check each one? It seems if they wanted some really useful info they'd put each of them on the same profile as you had (maybe with separate logins) and stick a samknows box on each of them, and then be able to compare like for like at exactly the same point in time.

There certainly was physical disturbance to both fibres when the new line was put in, both at the house end and where it joins onto the 'pit' at the end of my drive. I agree, it would have been cleaner to leave me on GEA, but I actually need connectivity to work, so that route had to be followed! It is also more than possible that some exchange equipment has changed, there have been occasional outages suggesting other changes are afoot.

I am running both simultaneously, but the 'new' line has my main stuff on it, and the GEA (old) line has just a MacBook Pro running occasionally Fast.com's etc. I would certainly have liked to be party to Zen's testing schedule (that's my job actually) we could have had a proper plan to establish a proper baseline, and move things on one step at a time in a methodical way, but there you go, not my call. Will be just one SK Box on the old line, and I await their requirements for testing. I have two profiles, the one on the old line is Vanilla, and my real profile has my own fixed IP and domains pointing to it (to ensure business as usual), but swapping is trivially easy. I really hope that the old line can be coaxed into giving the same symptoms I saw (and so did Zen).

So, my SamKnows box is now running, and my old line has been GE Migrated back.... What does it look like? SamKnows box output Seems pretty darned stable doesn't it? So, what's different? Any comments anyone?
