Jul 19, 19:02 UTC

Update - We have completed two test runs to revert the resource resolution URLs of the DOIs affected by this mistake. Both tests have gone well, but turned up problems with our reversion script. We're currently running a third test run and will begin reviewing the results of that test later today. While we'd love to get the reversions to production resource resolution URLs kicked off as soon as possible and revert all of the mistakes now, we have decided that running additional tests is the best option for all affected members. Thus, we will not begin the reversion on production resource resolution URLs until Monday, 19 July at the earliest.

Update - We are currently going through the results of our test run to revert all of the affected DOIs' resource resolution URLs to ensure there are no errors in our script. If that review goes smoothly, we should be able to begin the reversions in production starting tomorrow.

Update - Our technical team continues to work on testing the URL reversion script to ensure that it is making the desired reversions and only the desired reversions to the affected content. We'll begin reviewing test results as a team tomorrow and hope to kick off the resource resolution URL reversions of the affected DOIs on Friday, 16 July.
Jul 14, 17:17 UTC

Update - Our technical team will begin testing their script to revert the affected resource resolution URL later today. We're still looking at the second half of the week before we begin making URL reversions. We have also confirmed the list of all affected DOIs and will be sharing that with the 22 affected members shortly.

Update - Our technical team is continuing to work on a fix. We're anticipating reverting the incorrect resource resolution URLs of the over 1.1 million affected DOIs during the second half of this week. This is the first time we're attempting a reversion of resource resolution URLs, so we're taking our time to ensure we get it right.
