It went down for me around 10pm BST last night. I assumed I had hit a data limit or something. This morning I checked their website, their twitter feeds, google news and found nothing.

So i phoned them at exactly 8am this morning. I was on hold for 47 minutes. Turns out its not just me.

Extraordinarily disgraceful communication with customers about this. They should be completely ashamed that they had a 12 hour outage they refused to publicly acknowledge. I can forgive the outage but the outrage of their poor communication is sad

I'm tired of the Three coverage and "uptime". Fine, now they're down, shit happens, I can deal with it.

What pisses me off is their permanent shitty signal - enter a supermarket - no signal, enter a data centre (at work, where I spend most of the day) - no signal, go in a building with thicker walls (e.g. Barbican) - no signal.

In all these places Virgin Mobile has no problems.

What's amusing (for me) is the first I heard about this was via their Twitter account - I was on the internet at the time using their data network, having just turned my phone on!

Three seems fairly reliable, with a decent signal strength in my area, compared to O2/giffgaff (which my friends like to use).

Their support on Twitter is fairly quick to respond, but I suppose that's more indicative of the way support over social media is nowadays.

I'm always surprised that intelligent people are shocked that the consumer cellular network they pay £5 a month for doesn't have 100% uptime

I noticed I had no data at around 23:30 last night and still no data at around 8:30 this morning. I was pretty surprised to see the outage last that long.

Things appear to be working again now (12:30) albeit slower than usual.
