Various pages on the kernelnewbies.org website throwing 502 errors

I was trying to navigate to some pages on kernelnewbies.org and I got 502 bad gateway errors. The homepage works sporadically, but others throw the error mentioned. Examples include: - https://kernelnewbies.org/OutreachyIntro - https://kernelnewbies.org/FAQ - https://kernelnewbies.org/Documents - https://kernelnewbies.org/KernelJanitors - https://kernelnewbies.org/KernelProjects I apologize if this information is redundant: I just subscribed to the list.
