Anyone noticed Zen throughput oddities today?

Off the back of issues with my GEA connection (since migrated back to BTW) I'm in a heightened state of vigilance, and I'm noticing some reduced throughput on some of the Zen gateways today, yet oddly on one of these gateways (vt1.cor1.lond2.ptn.zen.net.uk) I'm getting higher throughput than I've ever seen (930Mbps+) to one speedtest server in particular - VoiceHost Norwich. While testing Zen's own server on that gateway doesn't reach 800Mbps anymore.


Anyone else notice anything?

hi sorry to open old thread - did Zen do a rollback to the GEA migration and put you back on the previous config ? thanks

Yes, he says so on the 1st line in his post.

Have a read of the very long Slow speed after GEA migration thread.

It details multiple users who have been migrated to Zens own GEA network and have suffered large drops in throughput since.
Some of those users were migrated back upon request.
Some of the users had a free 2nd line installed by Zen in an attempt to fix the problems (unsuccessfully).
Some users have simply left Zen.

We've already seen Zen customer service reminding a number of customers that the minimum guaranteed on their full fibre 900 is 450Mb/s.
So technically Zen can do nothing and tell your that they are meeting their obligations.

Eventually Zen will want all users on their own GEA network wherever it is available. So at some point they will presumably start refusing to migrate customers back.

I started on BTW. Was then migrated without my request to Zen GEA. After a couple of months complaining about the performance issues, I was moved back to BTW, and my issues cleared up instantly.

Unfortunately it appears all Zen's infrastructure is held together with wet bits of string, and their system promptly auto-migrated me back to Zen GEA less than a month later. D'oh!

They said someone hadn't put the flag on my account to stop future migrations, and did I want migrating back to BTW; but I was done at that point, it had already been a colossal waste of my time jumping through hoops to furhter show them what I knew all along - they'd made some change in moving to Zen GEA which was a big performance hit for me. They allowed me to exit contract.

I'm now with AAISP and very happy.
