+# Notes
+
+- The CI master server is responsible for updating the CI check status to
GitHub in each of the PRs. Using EC2's default DNS sometimes result in DNS
resolution failure and thus a failed status update. It's better to have
multiple reliable DNS servers as backup. The following servers are recommended:
+```
+1.1.1.1 # Cloudflare
+8.8.8.8 # Google
+208.67.222.222 # OpenDNS
+```
