I've certainly had one not too long ago...months rather than years but I can't be more certain than that.

I'm definitely thinking months rather than years ... I reckon probably about September last year, but I don't know how I could check that.
I do know that there have been plenty of test failures since then for which I have received no notification.

It would be a pity if they've done away with that service.
However, it seems that their matrix is now more reachable - which is definitely a step in the right direction.
(I've had some really frustrating times in the past trying to access the matrix, but lately it has been quite good.)

Cheers,
Rob
