Anyone notice a slowdown in googles functionality?

Not so much their "Search" and standaer user tools but on the back-end? The API aps and webmaster tools.

Sitemap approval seems to take a little longer, new website validations take a little longer, They almost always have the "server maintenance" warning up and from what I can tell... At this moment, Google's adsence is hanging up on a few sites. (adserver.googlesendication)

And anyone know when the last deep crawl was?
