GMail is having issues again

Many reports (including from myself) of people being unable to

1. Send email

2. Upload attachments

3. View attachments

The status page isn't showing any errors, either http://www.google.com/appsstatus

Edit: My important email was finally able to be sent after 20 minutes of "server errors".
