Timeouts and timing phases
All API checks are capped at a timeout of 30 seconds. With each request, we record the most relevant timing phases. This can help you troubleshoot slow responses, e.g. your DNS might be slow.
The timing phases correspond to the Node.js request library timing phases:
wait: Duration of socket initialization
dns: Duration of DNS lookup
tcp: Duration of TCP connection
firstByte: Duration of HTTP server response
download: Duration of HTTP download
