This incident has been resolved.

We have a deployed a fix for the IMX Marketplace and have confirmed it is now showing all collections.

Due to an earlier issue with Github (see: https://www.githubstatus.com/) the github API began serving the incorrect version for some repository tags.

We have deployed a fix for the marketplace to lock to the current version and we are continue to monitor.

In addition, our global CDN cache has been cleared (this may take up to 15 minutes to propagate through Edge locations)

We have identified a related issue with the github api and the fetching of images.
See: https://www.githubstatus.com/
We are working on deploying a fix to the IMX marketplace frontend.

This issue impacted the homepage of the IMX marketplace only.
The IMX API is not impacted.

We are currently investigating this issue.
