Initial Problem Description 
Google released an update to their +1 button script sometime on Tuesday (10/25/2011). This new script had a line of code that interfered with most JavaScript frameworks. This script error only affected some of Internet Explorer browser users. Sometime on Wednesday night (10/26/2011), Google appears to have rolled back their script changes. Google has made no official announcement that references the problem or the original update that caused it. The only information about the outage was gathered here:
https://groups.google.com/forum/#!topic/google-plus-developers/lOt_NJ2j7P8.
In this forum, the problem was confirmed on Google’s developer discussion group and was escalated by a Google support engineer around 10am Wednesday morning.
Effect on a website
Any page that loaded the Google +1 script would encounter script errors after the button had rendered.
