Timeline (UTC)
Cause Analysis
The incident intialized when Adform, a Prebid Server Adapter/PSP demand partner, removed support for several optional parameters in their adapter. We made an update to reflect this change, however, this did not automatically update the existing configs containing the optional parameters.
Resolution Steps
Bulk edit of the new Adform parameters from integer to string resolved the issue affecting the Prebid server premium calls and re-uploading all of the Adform parameters resolved the remaining.
**
Next Steps**
* Add validation to the bulk edit process to ensure expectation is matched
