Sadly getting exactly the same thing here too (Luton area) since around yesterday, although getting worse at the moment.
Pages start loading and stop. Pages sometimes fail to load at all. Internet seems to be generally disappearing and coming back up at occasions too

- I'm hoping it's just something temporary and it'll pick back up again. The recent month or so has been pretty bad compared to the normal great service from NTL. This month, I've had many disconnects, failures, losses of internet access, slowness and random ups and downs. Still, hoping it's temporary.
Glad to know perhaps I'm not the only one getting this.
