Blogger turns out to be very similar to the NHS- free at the point of use, but wildly unreliable.
So under advice from Colonel Blimp I've decided to switch to what I now understand to be the BUPA of blogging- ie Typepad.
I'm annoyed about all the posts and links I've already got on Blogger, but I can only blame myself. A free service sounds too good to be true, and guess what- it is.
At least with Blogger I can move on without being forced to pay for a service I'm no longer going to use.
Unlike the NHS.
