Webmaster Central Site Verification

I mentioned a couple of days ago that the site verification with webmaster central was down.

Having logged in this morning I saw the same warning. As a test I simply re-verified a couple of my listed sites and that seemed to work fine. Then I noticed that there was an erroneous first entry of:

Manage http:///

I selected it, deleted it and wham! all of my listed sites are now successfully verified.

A bug in the system or is google monitoring who actually uses their webmaster central account? Most probably the former!
