Yep! Must have been doing it about the time you raised this request.

It was my error in the first place; I responded to a UR saying it was down to 50 for roadworks without checking carefully enough. Although I thought I found a Highways England (or whatever they are now) posting on one.network saying there would be a reduced speed limit.

There was certainly no sign of roadworks or speed limits (beyond the permanent one at the M25 junction) when I drove the road yesterday.

Anyway, it's now back to 70 on WME, although there will be the usual delay before the change goes live - most likely sometime tonight.

Looks like another editor has already dealt with this.
