What happened?
community.zimaspace.com (50.16.36.123) is unreachable.
DNS resolves correctly but TCP connection to port 443 always times out.
Tests performed:
- ping: no response (likely ICMP blocked)
- curl: connection timeout
- openssl s_client: no handshake
- mtr: route reaches Cogent backbone then stops
Likely server-side issue (AWS instance / firewall / load balancer).
