Signature and PDF Markup Errors

This incident has been resolved.

We have implemented a fix that resolves these issues and are monitoring to ensure no ongoing issues.

This issue will affect the following:
- Signing a checklist or test signature line or a signature block will fail.
- Attempting to create or update a profile's saved signature will fail.
- When annotating a PDF or image, a red banner showing "503" will appear. The annotation is saved but when generating a report that includes the file the annotation will not be shown.

We have identified an issue in the application with saving new signatures and generating updated PDFs when annotations are added. The source of the issue is a component that generates new PDF files on demand returning 503 errors. We are working to resolve the bug and restore service.
