As part of our ethos to build a better web, our team always strive to do what’s best for both our service and others. Therefore, Netlify have recently deprecated the ability to create open proxies. What is an open proxy, I hear you ask, and what’s (possibly) so bad about them? Well, rather than rei…

:wave: author of the post specifically called out above. I noticed that this functionality all of the sudden stopped working and was wondering why . [image] Scott: We identified only a few dozen customers who had configured an open proxy, whether intentionally or by accident. All customers wit…
