response on Wordpress

The illustrious, flawless, indefatigable Wordpress.com just gave me this response:

Server Maintenance

Your server is going through a few minutes of routine maintenance. Please don't touch your browser for a few minutes.

What do I do?

• If you were posting a comment or making a post on your blog then do not press BACK on your browser. Wait 5 minutes and press the refresh icon on your browser. Your comment or post will be sent as normal.
• If you are browsing a blog here just wait a few moments and hit refresh. The page you were expecting will appear.

Please do not hit the BACK button on your browser!
