GeoCities will close later this year.

Why is GeoCities not accepting new customers?

We have decided to discontinue the process of allowing new customers to sign up for GeoCities accounts as we focus on helping our customers explore and build new relationships online in other ways. We will be closing GeoCities later this year.
I'm a GeoCities customer. What's happening to my site?

Existing GeoCities accounts have not changed. You can continue to enjoy your web site and GeoCities services until later this year. You don't need to change a thing right now — we just wanted you to let you know about the closure as soon as possible. We'll provide more details about closing GeoCities and how to save your site data this summer, and we will update the help center with more details at that time.
Will something happen to my GeoCities Free or Plus account?

Later this year we will be closing all GeoCities accounts and web sites. We'll send you more details this summer.
Can I prepare for GeoCities closing now?

All of our GeoCities customers can continue to enjoy their sites and GeoCities services until later this year. You don't need to change your service today, but we encourage anyone interested in a full-featured web hosting plan to consider upgrading to our award-winning Yahoo! Web Hosting service.
