Cuckoo transfer to Onestream

Got the email this morning (well yesterday actually, except that GMail spammed it and I didn't find it till today). As reported on TBB here and ISPR on 11 May. Email reproduced below. It seems it's going to be some peculiar mixture of both Cuckoo & Onestream, at least for now.

It's been a bumpy ride since the heady days of Swish Fibre 5 years ago, and it seems it's not over yet. It says broadband services will remain the same, so I will have to see. If recent reviews of Onestream on reputable sites (ie not Trustpilot) are to be believed, then it looks like it will soon end in tears.

If only OR would get a move on and complete their build here.

Transfer of Cuckoo customers to Onestream

Hi XXX,

We are writing to let you know that Onestream Ltd (“Onestream”) will be taking over responsibility for providing internet services to you under the Cuckoo brand.

Whilst you will continue to receive Cuckoo-branded communications and special offers, your contract with Cuckoo Fibre Limited will transfer to Onestream Ltd, as permitted by your contract terms, with effect from end of May 2026. However, you don’t need to do anything, as this transfer will happen automatically and there should be no change to the quality of your service.

We would like to take this opportunity to thank you for being a customer of Cuckoo. Onestream will be in touch to introduce themselves.

And as a welcome present from Onestream, the IPv6 stack has stopped working. Went down at 7am this morning when the router failed to renew its v6 address. Has an address back now but nothing works, and it's affecting Android apps so I'm going to have to disable IPv6 at the router again.

It's going well so far.

Ive been unfortunate enough to have had a few ISPs over the years that have been taken over while i have been with them.

Never ends well.

Two for me, Metronet was taken over by Pre-BT Plusnet, I left a week after the news came out. The other one is Zzoomm, which i am on now, they were taken over by Full fibre.
Zoomm for me have been okay, but they are not in my good books at the moment.

Slightly different as both Zzoom and FF have different areas covered and as alt nets own their own infrastructure.

I was with Metronet and also left back then, but this was in the ADSL days!

That is true, but still a different company and things may change.

Doers it make any difference what days it was back in that Metronet was taken over? Apart from maybe dial up as that was easier to change to another provider.
I liked Metronet, I liked the idea of it, not sure how it would work these days, but maybe for people who say like my brother who only use a few gigs a month it may.

I liked Metronet too. If you need to ring support, there was a half decent chance you’d speak to someone you already ‘knew’.
The product was good. The customer service was belting.

Only that in those days the costs of the network were significantly lower as everyones speeds were lower, and the cost of the connectivity to the local-loop provider was pretty much only the one choice in BTwholesale. Things have changed, speeds have more than quadrupled.

I think there are the smaller, more personal and customer service focused companies still around, perhaps Aquiss for one.

I wish I could jump ship too, but right now I have very few options. OR are building - frustratingly there is a shiny new CBT on the pole outside - but there's no indication that there's any light to it, nor when there might be. OR checker status is still building in the next year, as it has been for a year now.

Trooli are here, but I witnessed their build quality 4-5 years ago, all done by subbies, and that was one of the reasons I went with Swish. And at the time Trooli wouldn't let me use my own router, but I think they're more relaxed about that now. I think there are a handful of ISPs now that use the Trooli network? I don't want another splice box and another cable to the house and hole in the wall for what would likely be an interim solution.

The rotten old mixed Cu/Al OR line is still here. Never did more than 30Mb/s FTTC, usually nearer 20 if it was either raining or the sun was shining. Constant battles with DLM continually reducing the sync speed, which I hoped were a thing of the past. But it might have to come to that for a short time.

I was hoping OR would complete their build before Cuckoo blew up, but that hasn't worked out. Cuckoo's fibre service was actually very good and reliable. It's their CS that was/is diabolically awful. I just kept my fingers crossed that I didn't have to use it.

it's funny Jurassic fibre switched to cuckoo. And again after few years now another company takes over. Story never ends. Probably prices will increase later and network becomes more unstable and even worse . Happy times. Cuckoo uses altpointfibre anyway and network quality is really bad constant disconnections speed drops for no reason.
