I have had Intermittent problems with DNS as well since Monday but Tuseday was the worst day.
Im starting to get a llite fed up with it know.
Having the same problem here in Lisburn Northern Ireland, the DNS issue here seems to be one that does not stop and does not appear to have a period where everything is working fine, something is always wrong, takes me many attempts to load up websites, sometimes they will half load. How long does it take to fix an issue like this, it seems like something happened when they went ahead and blocked all them websites 😞
South East, also having this problem with unable to resolve host intermittently on random sites. Right pain in the backside.
Still a problem here too (South Oxfordshire). I was hoping this issue would get resolved within a reasonable time scale to avoid messing with any config settings but I've now just resorted to changing my Windows IP Config settings to use the Google DNS servers. Since doing that everything seems to be fine.
Same problem on and off for the last 4 days. (Warwickshire) At first I thought it's cyber Monday - but this has been happening for days.
Affects a lot of https sites, but also you tube.
Tried to flush dns, reset router.
Definately not my PC, as it happened on my phone via wifi also (eliminating home plugs and PC).
I switched wifi off on the phone, and refreshed page that refused to load, loaded straight away on mobile (non BT network)
Has some kind of network upgrade happened and it's gone wrong?
I'm using Home Hub 3 (I think) so I don't I can using Google DNS?
I'm on a HH3 as well. If you Google "Using Google Public DNS" the first result returned will tell you how to change the DNS that your computer uses. This will override what the hub is trying to use.
