- postmortem
# Postmortem # **What happened?** On January 22, 2024, 07:38 UTC, some Web Folder requests to the imgix service began to return a `403` response. By 11:56 UTC, the issue had been completely resolved. # **How were customers impacted?** Between 07:38 UTC and 11:36 UTC, several requests to web folder sources began to return a `403` error. This affected a small amount of assets \(<0.1%\). # **What went wrong during the incident?** A service update caused an issue with web folders with directories using double slashes at the Origin URL \(`//`\). This update caused an encoding error, leading to `403` responses for Origins matching the double slash pattern. A fix was pushed to resolve this URL pattern, allowing us to fetch images from affected Origins. # **What will imgix do to prevent this in the future?** We will update our tests to catch encoding issues in the future.
