Sorry to hear it! What happens when you ping other addresses that are publicly available, such as 8.8.8.8 (google DNS server) or 1.1.1.1 (cloudflare DNS server)? I’m looking to understand if you have slow/flakey network access to everywhere outside of China, or if it is somehow specific to one or more of our IP’s.
