Again, what dev tool are you using that get blocked because of these blocks? Is it Vercel you're unable to use during the blocks? Because my local Vercal installations keeps working just as well with no internet as with internet, so I'm guessing some Cloudflare IPs going offline won't have any effect either.

You again reference blog posts from more than a year ago, the situation here in Spain isn't the same today as it was back then, it isn't blocking as much as it used to, and surely if you're personally impacted by these blocks, like I am, then you'd notice the difference today compared to before?
