Systems Maintenance on June 22

For WMS and Web service authentication infrastructure updates

Web services that require user level authentication will be down for WMS and Identity Management system (IDM) updates beginning Sunday, June 22nd, 2:00 am EDT. This will affect OCLC’s worldwide data centers as follows:

US & Canadian Data Centers: 22 June 02:00 Eastern (EDT)
European Data Center: 22 June 07:00 Central European (CET)
Australian Data Center: 22 June 17:00 Australian Eastern (AEDT)

We anticipate all services to be restored by 09:00 EDT / 14:00 CET / 24:00 AEDT, but may require an additional contingency until 12:00 noon EDT to complete testing.
