I had a problem with Zen recently-ish too. Ultimately was an Openreach thing at the local exchange apparently. The good Zen support was still ultimately there, but it took a little time for things to fall into place. Standard L1 checklist inflation. Thankfully though Zen are one of the few ISPs where I felt like it was worth it to send packet traces because a decent chunk of folks there would know what they are.

On the other hand, I think any ISP at the mercy of openreach is doomed to have limited support.

I have fibre to the property, and was having periods of 1hr-2hr day of my gigabit speeds dropping to 4-5MB. openreach themselves were blindly sending engineers to look for an issue that couldn’t physically be at my house.

Not much you can do there either as an ISP or as a customer besides wait for openreach to figure out they’re wasting their own time
