My first thought was that they’d accidentally broken their BGP announcements, cutting themselves off. I don’t know enough about this topic though: are you saying there’s evidence they just stopped announcing their networks for no real reason, or is this graph a symptom of someone being something else being wrong, as opposed to being the root fault?

That's one of the reasons I kept my Irish SIM even after I got my Danish one. I've found it useful on plenty of occasions to switch to the other, especially when traveling.

I could tether to my (non Vodafone) phone, but my work laptop refused to connect to the WiFi hotspot until I physically unplugged the ethernet cable from the dock. "You can't connect to another network while you're on your employer's network." I'm not!

I had a similar event a few months back, I now have separate providers for my SIM and home internet.

You pay more, but the redundancy is worth it imo

I'm not sure that would necessarily have helped. My regular sim was on another network (giff gaff), that was down. Went out and bought a pay-and-go sim on yet another network (EE) - no dice there either. Not sure what the issue was, but it seemed to have knock-on impacts in areas like mine that were affected.

> I hope we get more info or a postmortem.

You're a funny one.

Have you experienced how impossible it is to get decent tech support out of Vodafone these days ? So chances of a postmortem ?

I also use an MVNO service.

I have a horrible feeling that 3 traffic is being prioritised over Vodafone MVNO traffic, leading to service deg.

End of the day, I was on Vodafone's network for a reason - it was the least congested in my area. 3 was crap. If I’m suddenly fighting for bandwidth with 3 customers because of this merger I will have to try EE (o2 is known garbage around here; 2 mbps at most thanks to traffic management).

Ofcom should never have allowed it - the UK does not need reduced competition in this space.
