Over the past 8–10 weeks, the situation has worsened significantly. I’ve found myself unable to use the site during evening hours. I’m skeptical that Bambu Lab can resolve this unless they reconsider using Cloudflare.
From what I understand, the issue lies with Cloudflare’s routing, particularly in Germany. Apparently, Cloudflare requested fees from providers like Deutsche Telekom to connect directly to their network, but Deutsche Telekom declined. As a result, traffic from Deutsche Telekom’s customers is routed through less favorable paths, often via US servers, and is deprioritized. This leads to especially poor performance during evening hours when US traffic is high.
To work around this, I’ve been using a VPN, which has made the site usable again without any issues—no need to even switch countries. Since this doesn’t appear to be an issue Bambu Lab can address, please consider this matter closed.
