We don’t maintain a comprehensive list, but here’s the general rule:
Static proxies typically block access to banking or payment systems, certain government (.gov) sites, as well as marketplaces like Avito, OLX, and Kufar.
If you need to access a specific site and aren’t sure whether it’s blocked, feel free to reach out to us for clarification.
Other websites that we have disabled on our end:
Apple.com
