People on Twitter report Google Docs ouatges during the last 2 hours. My Google Docs is down for a few minutes now. How about you? Can you use Google Docs? Also other Google services seem to be occasionally down too.
Just yesterday I had Google Analytics issues.

Only presently is down for me right now.

Seems like Google is aware of it : http://www.google.com/appsstatus#hl=en

Thanks for the feedback Jeremy.

Creating a new presentation works here, France.

Current status: "The problem with Google Presentations should be resolved. We apologize for the inconvenience and thank you for your patience and continued support." It's working fine here.

The only reason why I don't trust cloud computing: they're down but you need them most. Gladly, there will always be a free and offline OpenOffice. :)
