From WorldAPP, creator of the KeySurvey product:

“WorldAPP will be releasing V8.0 of Key Survey/Extreme Form on December 24th, 2011, between the hours of 1:00 AM and 11:00 AM EDT.
Individuals attempting to access surveys/forms or accounts will see a a friendly notice during this time. When the work has been completed all individuals will be able to access their accounts and links normally.

We have launched a special web-site to make sure you have all the information in one place in case you need it – www.worldapp.com/v8_0/
(Note – there are short videos here showing features of the new version)

To see the complete list of improvements, please read through our noticeable changes document – http://docs.worldapp.com/User_Materials/V8_0/Change_log_v8_2011.pdf ”

All current surveys and responses will remain unchanged in the new version. Overall, there are some nice new features and clearer page layouts, but it still is recognizably the same and should be intuitive to use!
