Do you use Home and Kids safe?
If so try adding the links to the allow list, then once having saved then, reboot your router (preferably turning it off for 30 minutes to start a new session), close the browser and when the internet is back on, try again.
If you don't use home kid safe try changing the DNS values on the router to those used by Google. 8.8.8.8 and 8.8.4.4.
If you use home safe changing the values mean this will not work as it relays on TalkTalk servers.
We've recently had a situation where a website was block by TalkTalk as they reported malware being present, so the site was blocked for customer security.
Staff are not back until Monday now so won't be able to check those you've mentioned, so hope in the meantime the above may help you access these sites.
Please remember to mark Solved Posts with Best Answer. Doing so helps other customers and saves TalkTalk's Support Team time by only looking at unsolved topics. Thanks, Steve (a fellow customer).
