To reply to myself.
I swapped the router for a spare ADSL router and found that all
the sites that had not been accessible were now accessible. As it
wasn't an ASDL2+ router my connection speed fell by more than 50%,
but at leas it confirmed it wasn't an issue with any of my PCs or
my ISP.
I factory reset my old router and reconnected it to my ISP - with
minimal configuration - and it still had issues. I can't flash the
router as it's not an off-the-shelf model but an old ISP "tweaked"
version that will not accept the latest OEM standard firmware.
In the end I bought a new ADSL2+ router, configured it to my ISP
and all is now well, I've got proper connectivity and it's even
marginally faster than the original ADSL2+ router.
