What are some URLs that were detected by the firewall?

Operating system

Linux

Joplin version

2.13.8

What issue do you have?

When I open Tools -> Options in Joplin Desktop for Linux, I notice that Joplin wants to connect to some servers:

raw.githubuercontent.com
raw.fastgit.org
cdn.jsdelivr.net
us4.ghproxy.com
cdn.staticaly.com

Can someone explain what are they for?

Screenshots

Internally, Joplin maintains a list of GitHub mirrors that are used if Joplin is unable to fetch plugin data with raw.githubusercontent.com. Plugins are stored in the joplin/plugins repository.

This is the relevant code:

All URLs should be listed here:

Thanks for two pieces of information!
I trust open source code!
