I tried to update CachyOS just now and it couldn't resolve the domain name.
Swapped out the malware filtering DNS Quad9 for whatever the default DNS is and it worked fine. Sure hope this doesn't mean anything.
i just used a third-party mirror. found one that was better and faster than ubuntu's own ever has been for me:
https://launchpad.net/ubuntu/+archivemirrors
in case launchpad isn't accessible:
https://web.archive.org/web/20260425125013/https://launchpad.net/ubuntu/+archivemirrors
for 'ports', see here as well, which directs you to this mirror:

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
