Login problem end of last week

[A Stuart]

Anyone tech-minded out there?

Did anyone else have problems logging on over two or three days at the end of last week?

I was asked whether I was a computer and faced with this impenetrable Captcha which took twenty-plus attempts to get through, and the same the next day, now back to normal, logging straight back in using exactly the same shortcut as always.
I am concerned to know whether this was just a change with the website, or whether my computer was either malfunctioning or causing my IP address to be logged as a source of some malicious behaviour.

This coincided with other small oddities which I would have forgotten individually, like BBC iPlayer asking who I was.
