Lot of 404 errors from GitHub

[jcubic]

Describe the bug
I have all https://jcubic.github.io/lips-test/ and it's broken because of jsDevlr it keep returning 404 and I can't fix that myself becuase of rate limit of purge. I will need to purge every URL from github I use to fix the issue I've fixed one URL now I'm blocked.

We are also getting 404 errors on a subset of our gh assets, the behaviour seems inconsistent.

For example:

https://cdn.jsdelivr.net/gh/fonsp/Pluto.jl@b29f293/frontend/components/Editor.js

gives a 404, even though it is listed in the directory listing:

https://cdn.jsdelivr.net/gh/fonsp/Pluto.jl@b29f293/frontend/components/

and other files inside the same directory, with the same commit hash, work.

Note that unlike #18289, I am also getting reports about 404 errors on git commits that are not recent, the example above is a commit from 6 days ago.

We are looking into this right now. I will have an update soon

The issue is limited to new uncached files hosted on Github. The reason is that we hit their rate-limiting mechanism because of abusive behavior originating in Hong-Kong.
We are working on fixing this asap

I believe everything should be back to normal, we fixed the issue a while ago.
Our multi-layered caching prevented this from becoming a big problem and only new requests for new files should have been impacted.
We blocked the abusive requests and now work on adding checks to avoid this from happening again.

I am sorry for any problems this issue caused and thank you for reporting

Awesome thanks for fast fix. It seems that for my case it works fine.
