"Dear Yahoo! GeoCities Member,
GeoCities will be performing scheduled maintenance starting Friday, May 17th, 2002 at 9:00 pm PST (GMT-7). Service will be restored the morning of Sunday, May 19th, 2002."
Geocities will only be taking down the free services-Geocities Pro, Webmaster, and Advantage are all un-affected.
TOP TIP : get all your stuff before it gets taken down!
