Hi Ivan, thanks for the message.
I am afraid that your guess is wrong; there is no such feature in the CentralNotice system to automatically check what HTTP code a website is responding with. I am also afraid that we have sent a few thousands unique visitors to a non-working website (I estimate the number at between 5 and 6k).
In the future, please inform me immediately about any problems you experience with your websites - via e-mail at odder.wiki@gmail.com or try to poke me at IRC (odder).
For now, I have turned off the banners in Mexico (because your website is not working anyway), and the .org has content only in English). Please inform me ASAP when your website is working again.
Tomasz
