In my opening post I said "For the last 5 days, BT BB has had bad routing, most websites will resolve, but not all load".

If its not a DNS issue, what is it then? I'd be interested to know.


I don't believe its a DNS issue as such (tho changing DNS can sometimes work around it due to more complicated reasons) - it seems to be an issue with some kind of packet inspection and.or caching/transparent proxy system or something along those lines that BT use.

Thank you for clearing that up, it all makes sense now. Just have to sit tight and wait.

I remember reading on the BBC Wales web site around 5 days ago of Police searching for people with burns injuries after a communications sub station was attacked. The clowns cut a very high voltage feed and caused an explosion.
Could this be the cause?

With all due respects, the HH is a single combined router/modem unit so I'm not sure what the heck your going on about. And no, its not a security issue, its purely a DNS issue at BT Retail servers, as I have already said. In fact, I cant even access the BT Service Status webpage right now, but if you look yourself, you'll see our exchange and a few others have been affected by this problem since Saturday and the issue is still ongoing. Seems like theres a serious problem.


Given as far as I can tell all BT ISP users in the UK are assigned the same DNS, and nobody else is reporting issues (yes, I'm a BT customer using Infinity) the questions go to your hardware (the homehub) and/or your PC. You've not yet ruled out any problem with either or those, either using a third party router, or trying a friends PC.

If BT has a status issue for your exchange area on the site then perhaps wait until that is cleared - or if its not cleared phone them and ask for money back for not providing the service you're paying for.

Thanks, it seemed I was getting DNS and server caching mixed up, I learn something new every day. As this outage has affected others in the immediate area and the BT Service Status is apparently showing issues, I'm going to wait for it to clear. The hub is only a few weeks old, and 2 laptops, 1 desktop and 3 mobile devices that connect to it are having the same problem, and like I said, others in the village have told me of the same problem, which is why I've ruled out a hardware fault. I've done the usual - hub soft reset, hard reset, used the master socket, tried different microfilters, tried a spare modem router, all to no avail. The hub is on default settings, so nothing has been messed with.

I'll look at getting some money back, thanks again.

I've never seen any web proxy caching on BT products, but then I've only used BT Business ADSL, and domestic BT Infinity - never domestic "BT Broadband" myself.

I'll look at getting some money back, thanks again.

Good luck with that.

No, you were getting DNS and routing issues mixed up.
