Zen outage this evening?

FTTP in Norwich City Centre.
Noticed performance wasn't up to par this evening, rebooted router and now no connection at all.
Checking in more detail; ONT LOS is fine, but PPPoE isn't working. Tried a laptop connected direct, also down.

Anyone else? I'm guessing yes by the queue on Zen's tech support number...

Well, got through on technical support, they did "something" to fix it and it started working again.
Confidence inspiring...!

Yes, also having problems (in Oxfordshire) on a Zen 900/110 FTTP line.

Repeated CHAP authentication failures, coupled with 80Mbps down, and just 0.6Mbps up.
Reconnecting repeatedly eventually finds a path that works properly at 900/110, but latency is poor.

This appears to be a general issue with Zen: ping latency for BT circuits here is ~5ms, but my Zen line is consistently 20+ms. Zen tell me that's acceptable, and yes it's a first-world problem... but anybody can see it's [censored]-poor for FTTP and indicative of poor architecture, routing, peering or some combination thereof.

Are you sure you haven't been migrated to Zen backhaul from BTW backhaul?

My performance woes aren't anywhere near that bad (I'm about at half line rate), but others have had that kind of level of performance issue kick in when migrated to Zen's own GEA network from BTW. Maybe that has happened to you.

As it happens, the reason for my issue last night appears to be because I've been migrated back to Zen's network (they put me back on BTW network at the beginning of the month to resolve my performance issues).

If you log into your Zen account on their website, and go to My Orders / Order History you will be able to see if you've had a migration happen - it will appear there as an Order saying something like: Zen FTTP GEA Migration Fulfilled on 27/09/2022.

I think if you are provisioned on a new connection on Zen FTTP GEA then you may not have any indication of that being a Zen GEA vs a BTW connection.

Funny I got bumped onto one of the high-ping gateways this morning when my (FTTC) line re-synced. I bumped myself back off it when I noticed. I'm on BTW backhaul.

BQM 29SEP

This week I've been seeing speed tests of a few mpbs down but usually full speed upload (central Bedfordshire) and issues you'd expect - I reset OTN and recovered, but seen it a few times since.

I have seen it when I run a speed test where something seems to recover but may be coincident

No, I thought that too, but nothing listed re: GEA migration.

Frankly, their shrug-like attitude towards these kinds of issues make me just want to switch away at the earliest opportunity. I know it's not an SLA-covered business line (and even if it were they've already told me they don't consider the latency to be a problem), but if it were my technical teams I'd have them drilling these issues until they were gone - the over-subscribed crapsicle that is BT should not be 5x quicker than an ISP that prides itself on quality!
