Service Unavailable https://www.w3.org/2018/credentials/v1 about w3id.org HOT 3 OPEN

Are you using proper caching? You should not need to retrieve that static resource for every VC. You did not provide the error you were hitting, so it's not possible to tell whether you were throttled out (i.e., the server may not like being hit too quickly, or too many times in a day, etc.) or ran into some other issue.

Certainly, that URI is working fine right now --

$ curl -LI https://www.w3.org/2018/credentials/v1

Agree about caching and this is not a w3id.org issue. Note that w3.org was using an expired cert yesterday for a little while, maybe around the time you filed this, and that may have caused certificate validation errors to happen that would cause an error like above. There may have been an error cause chain that would make that low level issue more obvious. I imagine it's working now but in general remember that networks and servers can have downtime and you need to have error handling in place to handle such situations.

For help with caching, I'd suggest the credentials community, JSON-LD community, or library maintainers. If you'd like better error messages, raise an issue with the library maintainers. I'm guessing based on that error message you are using jsonld.js or pyld, so that probably involves me, but better to discuss in another forum.
