Systems Maintenance on July 27

For application updates

All Web services that require user level authentication and the WorldCat knowledge base API will be down for updates beginning Sunday, July 27th, 2:00 am EDT. This will affect OCLC’s worldwide data centers as follows:

US & Canadian Data Centers: 27 July 02:00 Eastern (EDT)
European Data Center: 27 July 07:00 Central European (CET)
Australian Data Center: 27 July 14:00 Australian Eastern (AEDT)

We anticipate all services to be restored by 07:00 EDT / 12:00 CET / 19:00 AEDT, but may require an additional contingency until 10:00 noon EDT to complete testing.
