Notification: Planned Downtime During Aug 04 Maintenance - PP-LIVE-2189
Posted by PayPal_Updates on Jul 26, 2011 7:31:56 PM
NOTIFICATION: During this maintenance window we are expecting to have a series of short service disruptions:

- 3 minute PLANNED DOWNTIME between 11:00 PM PDT (August 5 6:00 AM GMT, 7:00 AM UK and 8:00 AM Central Europe) and 11:05 PM PDT (August 5 6:05 AM GMT, 7:05 AM UK and 8:05 AM Central Europe). The majority of PayPal API calls will fail to complete and return Internal error 10001 or Authentication/Authorization Failed error 10002. PayPal users will encounter error "Sorry - your last action could not be completed" when trying to log in to www.paypal.com.
- 10 minute intermittent service disruption between 11:05 PM PDT (August 5 6:05 AM GMT, 7:05 AM UK and 8:05 AM Central Europe) and 11:15 PM PDT (August 4 6:15 AM GMT, 7:15 AM UK and 8:15 AM Central Europe).
- 3 minute intermittent service disruption between August 5 12:05 AM PDT (August 5 7:05 AM GMT, 8:05 AM UK and 9:05 AM Central Europe) and August 5 12:10 AM PDT (August 5 7:10 AM GMT, 8:10 AM UK and 9:10 AM Central Europe).

While we do not anticipate any significant impact during the last two timeframes, merchants may experience some API slowness and some API calls may fail to complete.
