Oh, what a surprise ...
... TalkTalk has a problem and is just a little slow to admit to it.
TalkTalk-using readers have contacted The Reg to say they are suffering decidedly odd bandwidth issues shutting off, or severely slowing, access to certain sites while leaving others working as normal. A thread started yesterday on TalkTalk's support forum showed users unable to access iPlayer, ITV Player, All4, My5 and Alexa …
Some smaller ISPs resell TalkTalk in the same way that others resell Openreach. My small ISP, which I am otherwise quite happy with, does this.
Odd connectivity issues have been a problem for some time and very difficult to diagnose. Some websites seem to be affected while others are not, and those which are affected aren't always.
For example, last week I tried and failed to log in to my Amazon account even though I was able to browse and fill my basket quite happily beforehand. I had to re-do the order from scratch using my phone's connection. The week before, I had huge problems even loading up the front page of CPC which isn't normally an issue.
It seems to be an https issue - something goes wrong, data goes missing and the browser sits there for ages spinning away until eventually giving up, occasionally with some kind of 'secure connection failed' message.
Sometimes - only sometimes - clearing cookies gets things going, but only until the next time.

"Who's daft enough to go with Talk Talk?"
Sadly anyone who doesn't know better. Your average person with little to no experience with a variety of ISPs who watches the adverts on TV and is most swayed by prices.
Still - they're not Virgin. Who did the best ever thing... I had to help a family member discover why their net had stopped working. It turned out that there had been an issue caused by their credit card company. So Virgin shit off their internet and access to their email. And told them - VIA EMAIL - why they had done it....
Who's daft enough to go with Talk Talk?
Some of us in the USA only have access to one provider. This can be the case even for new housing construction. The options are to bring in a new provider for £10,000 or else suffer with a single provider. This is why you hear about individual cities trying to being in their own fiber, but then the city's fiber is a single provider again.
That could well explain the behaviour; if (for example) Talktalk have private peering to AWS and CloudFront then that link being at 100% might mean that Prime Video, Twitch and AWS-Hosted sites would be slow, while services hosted via other network links into TalkTalk would still be seemingly fine.
