Performance issues on upload
Incident Report for Codecov
The core issue has been resolved. The problem was due to a small change we made in our presigned PUT header signing process that led to the url being rejected in certain edge cases reports were inadvertently uploaded to a backup cloud storage solution that did not accept the modified header.

This issue has been rectified by ensuring the header change won't result in a rejected PUT when falling back to backup cloud storage.
