I assume you are just asking for clarification about the Far Side part of this, but for anyone who does not understand the It’s Always Sunny in Philadelphia part:

No, that was me too - I eventually figured out that looked like Danny DeVito's head, made the connection it was something about that Sunny show and shrugged. I don't watch that show so the context is/was completely lost on me, thank you for replying.

Can someone explain this to me and why it's being upvoted in Far Side comics area?

I was taught at an impressionable age that the only winning move was not to play. Advice that has not failed me in some 42 years now. Thanks Joshua!

To share a bit more because people think it was "good", the Battle of the Alamo was specifically because "About one hundred Texians, wanting to defy Mexican law and maintain the institution of chattel slavery in their portion of Coahuila y Tejas by seeking secession from Mexico, ..." (emphasis mine) https://en.wikipedia.org/wiki/Battle_of_the_Alamo

I cannot confirm that (I have nothing to do with lemmyverse), but it was/is up and functioning so my instinct is "yes, it does not use cloudflare".

I grabbed a quick screenshot hours ago showing the trauma; based on my recollection that I typed into the registration box of tchncs, these of the top 20 instances were all down: lemmy.world, sh.itjust.works, lemmy.dbzero.com, lemmy.zip, lemmy.ca, programming.dev, lemmy.blahaj.zone, infosec.pub, aussie.zone, readthat.com, lemmy.today. Sister sites on the piefed side (e.g. piefed.social) were also down because they're the same admins using the same tech stacks.

A lot of lemmy instances put all their eggs in one basket and found out.

While the downtime was most active, most of the top instances were down. Lemmy.ml, feddit.org, discuss.tchncs.de and behaw.org were all up. You can use https://lemmyverse.net/ to browse things and the ones offline all show a "content error" in lemmyverse.
