Google Crawl errors - All Pages drop - thousands of sites affected

in google crawl errors I have these 2 as examples (but there are many more):

Google Index:
http://www.dfordog.co.uk/charities_mayhew_strive_125.h..
http://www.dfordog.co.uk/didyouknow_parked_..

The real (complete) urls of these are as follows:

http://www.dfordog.co.uk/charities_mayhew_strive_125.htm
http://www.dfordog.co.uk/didyouknow_parked_cars.htm


2 ex: Google index www.mydomain.com! as the domain root
3 ex: Google index www.mydomain.com/sitemap.xml as the root domain in the Sitelinks

Someone has the same problem?

I hope this is settled, my main site has more than 5 years

Dmoz, Yahoo, and many more directories

Never use black hat techniques on this site

sounds like that's in-line with Google's dependability to most marketers...

Wow I hope they get it fixed soon
