31 March - test system - test.crossref.org - migration resulted in some members temporarily losing access and test notification callbacks being misrouted

   On 31 March, we migrated our test system - test.crossref.org - and brought it into sync with our production admin tool - doi.crossref.org. As a result of that migration, access to some of the test accounts was temporarily lost. In addition, members with notification callbacks enabled in test may have noticed that test callbacks were being misrouted to the endpoints set up for your production callbacks. We have since fixed both issues. If you're a test system user who is experiencing any issues today, do contact us at [email protected] so we can investigate and assist. - IF
