Funny you say that, was just in the middle of giving that a go.

If you have 1000 people per mast, and now have 3000 people per mast, for the same deployed capacity, then things will slow down.

How would that have happened over a period of two days last weekend? Has Three started sending out sim cards in the weekly junkmail?
The dramatic slowdown coincided with the disappearance of the note about dealing with "a complex network issue" in the area on the status page. Yes, it was also a weekend of very wild, wet and windy weather, but I think they have screwed up with the network redesign.
At first, some tracert tests showed multi-second delays a few hops into their network. Now they're only terrible.
I was foolish enough to contact Three support with help. All they managed to do was tell me to reset my router to factory defaults. as if that will affect their network capacity!

Here's a typical example: hops 4, 5 and 7 used to be visible until yesterday

My 4g has gone from bad to worse since this morning. Frequent disconnections, very less download speed, unable to connect to office vpn. I changed the apn to three.co.uk then got a usable link. Does it seems to common to any of you.

In my experience you can often get a temporary improvement just by resetting the 4G connection. Which happens when you change the APN.

So in my experience changing the APN to three.co.uk doesn't actually help, when I did it I thought it had helped, but after a couple of hours it was back to being intermittently poorly performing again. So I've gone back to 3internet again now, as having a real IP address and no NAT is useful some of the time.

I'm also investigating switching to EE though (where NAT will be the only option).

Won't EE cost rather a lot more for data?

My speeds are completely fine. Still getting around 60 down, 30 up on average. However, i have been noticing a lot more packet loss making online gaming and internet calls drop or become unplayable. Running a ping program clearly shows packet loss every 30 seconds or so with massive jumps exceeding 2k ms. Been happening for a couple of weeks now throughout day and night.

Same here for the past 2 weeks, god awful connection with inability to download/stream at the same time, Also times when it was so slow my router was connected but got zero bandwidth.

This morning first thing appeared much improved (download speed wise at least), I was back up to 50-60, and even saw it hitting an occasional 70mb/s, still the latency needs work, but it appears whatever they're working on they are heading in the right direction.

edit:
Just done a speed test now and we're down to 27mb/s though........

Still work in progress for Three then.....

It will, though I'm not on one of the mega cheap Three deals anyway, think I'm paying £27/month. So EE's unlimited option is only £7 more than I'm paying now.

And either of them are dramatically cheaper than the two bonded A&A ISP FTTC lines I had before...

But it doesn't matter how cheap Three is, if it doesn't work effectively. At the moment my connection is right on the borderline of being workable (I had it impacting a work conference call for the first time the other day).

For me things seem much improved and today latency has dropped to around 20ms:

I with EE and get both an ipv4 and ipv6 address (starting 2a01) when I check whatsmyip.com on my phone. checking the ip shown on my phone under device settings it shows the ipv6 ip (and a different ipv4 one of 192.0.0.4 which is not the ipv4 shown on whatsmyip). So I am guessing they are using both CGnat to give me an ipv4 address, and are also giving me a non-nat ipv6 address as well?

I am not sure if this is common for all on EE now or whether it is just because I have a business contract, the APN is "everywhere" which I do not think is business specific.
