On Monday StumbleUpon many users experienced a problem with stumbling and accessing their own SU page. Users may have seen a message that they have been locked out due to "Maximum Password Attempts".

Stumblers could not log in, nor could they access the help forum to contact the StumbleUpon staff.

The StumbleUpon engineers had rolled out a security update sometime Sunday evening or Monday morning that caused the issue.

The issue seems to have been fixed as of 2:14am on July 2nd.

"Update: the guys have made some changes to the machinery.

Please try clearing cookies (for "http://www.stumbleupon.com" - restart your browser - and try again. Should be OK now, but please let us know if you have further problems. We'll be here... (and watching Feedback, etc).

Please pass the word if you are in contact with other members who have been affected by this problem."

Being that I develop Internet applications I have much sympathy for the StumbleUpon staff and engineers. Many times we have found a show-stopper bug after deploying an application or update. It happens to all developers, it is akin to a Murphy's Law thing.

The folks at StumbleUpon fixed the issue quickly and I applaud them for their hard work and the ability to work under stress. With 5 million StumbleUpon users, I can see where an feature ends up being a bug that affects many.

Great work fixing it guys!
