Google AdWords: "Webpage Not Known" In Campaigns

There are a couple reports over the weekend of an error in Google AdWords where the webpages in your campaigns are being reported as "webpage not known."

The reports come via Google AdWords Help and Yahoo Groups.

One advertiser said his URLs and web pages are working fine adding:

I'm getting "webpage not known" Urls in the "websites" tab inside Conversions tracking.

Anyone has this same problem. Is this a bug? Am I losing real conversion urls?

Thanks for posting back. I will escalate your issue to the support team. Please be patient as their reply might be a bit slow due to the holidays.

I have not seen many complaints about this but I have seen numerous.
