NOTICE DATE:  May 11, 2010
NOTICE TYPE:  M-A051110-01 Extracts
SHORT DESCRIPTION:  Application Programming Interface (API) Query Results (pi.ercot.com) returning data other than requested
INTENDED AUDIENCE:  Market Participants
DAY AFFECTED:  April 21, 2010 to current
LONG DESCRIPTION:  Application Programming Interface (API) queries (pi.ercot.com) have been returning an index of files of Market Participant DUNS Numbers, Company Names, Filenames and Report IDs to Market Participant submitters beyond the intended Market Participant file request. This issue has affected both Wholesale and Retail Market Participants.

After researching the issue, ERCOT has determined that no Protected Information was visible and that extract data was not shared because of Digital Certificate protections. At this time, ERCOT does not believe any ERCOT Protocols were violated since the contents of the extracts were not shared with other Market Participants.

ERCOT has identified and is working to resolve the issue.  Market Participants will be notified with the implementation date and upon final resolution.
ACTION REQUIRED:  If any Market Participant determines that Protected Information has been shared, please contact your assigned ERCOT Account Manager immediately.

CONTACT:  If you have any questions, please contact your ERCOT Account Manager. You may also call the general ERCOT Client Services phone number at (512) 248-3900 or contact ERCOT Client Services via e-mail at [log in to unmask]<mailto:[log in to unmask]>.
