Large drop in AdWords Impressions 24th Jan

Anyone else seeing this?

[Pengi]

I'm seeing a large drop in my Adwords impressions today. Wednesday is usually my busiest day of the week, but today my impressions are down about 40% (lower than my usual week end levels).

Ad click through rate is about typical.

I've checked and don't appear to have had keywords going inactive due to minimum bid increases, and I seem to be recording both search and content impressions.

Is anyone else seeing a slow day today, or do I have I problem somewhere?

Any ideas?

There is another thread discussing the same problems. I have this same issue, but it started two days ago and still waiting for explanation from my adwords rep.
