There are alerts posted on Yahoo! help pages and this is an announcement just posted by @YahooCare on twitter:

We apologize for your inability to log in, and we are greatly appreciative of your alerting us of the problem.

Currently, some users are experiencing problems accessing their account. This is producing one or more experiences:

- Your Yahoo! ID doesn't exist

- Being on a "loop" on the login screen

- Your password is invalid

- Resulting in a blank page or receiving an Error Code

We are aware of the problem and expect the issue to be resolved within the next 2-6 hours.

During this time, you do not need to obtain a new password. Once we resolve this outage, you will be able to sign in with your current password.
