To be clear:
Again, this is NOT because of the update. Nothing changed in the update. If you get the old version, you still have the issue.
One person proved that above:

It has also been proved that if you use a different internet connection, the problem goes away.
So the problem, for the UK users, appears to be BT. The only possibility I can think of is that they are restricting http traffic from sources they don't understand. LFS connects with a "user agent" called "LFS" rather than "Firefox" etc. So maybe BT suspects it is a bot or web crawler. This is speculation.
Seeing as it's pretty much only BT users that have this issue, the ideal people to fix the issue would be BT, if they would kindly avoid traffic shaping that would be appreciated.
Alternatively we can try experimenting, so that LFS 'spoofs' its user agent to try to appear like Firefox. But I am seriously much too busy, currently working on average 12 hour days to try and get this release finished, so I can't start messing around now trying to get around BT's traffic shaping.
