Since the deploy of the new banner loading code, using document.write() within a CentralNotice banner can occasionally cause the page to be replaced with the contents of the document.write() function. This only happens every once in a while and thus is likely to be the result of some race condition in Javascript loading. Requires more investigation.
Since there is no safe way to include document.write() elements we've communicated to our banner authors that they should not be used.
