I have been a member of the Prosper developer mailing listing since the list’s inception… This is the 1st instance of using the list. They made the relevant announcement. Kudos! (it is about time) Here is the email…
Prosper is experiencing two issues that may be affecting your applications and code.
1. The web service API has been temporarily disabled due to a performance issue.
2. The XML data dump has at least one illegal character in it.
We do not currently have an estimated time for the fix, however we are actively working to resolve both issues quickly as it is impacting many customers.
Sorry for the inconvenience and we appreciate your patience.
