There is a new message posted on the UA homepage:

united.com site maintenance

During scheduled maintenance, several united.com features will not be available. At this time, you will not be able to:

* Purchase tickets
* Check your Mileage summary
* Update your profile
* Check flight status for airlines other than United
* Access your united.com itineraries

We apologize for the inconvenience. Please check back soon as these features will be available again shortly.

Umm...what can we do with the website?
