1500 ping is probably due to you being in Asia, typical ping is 600 (300 of which are strfry). Key not found sounds like service worker was off when you clicked Upload. Could you please reload the page and try again? Need to figure out how to wake the SW up if it starts sleeping with an open tab.

We're testing a secure enclave on Alibaba Cloud in Singapore, ping is 50-100ms. Testing AWS in Sing next. (Alibaba's enclave is basically a copy-paste of AWS, but their networking for SEA is very good.)

Is 50-100 ping from inside the enclave? Does enclave have network access by default or do you have to set it up somehow?
