Check a site's downtime with this bash one-liner
During a site’s downtime, the following line will print the current time and try to access the given URL one time every 2 seconds. Only the received HTTP headers will be shown.
You may find it useful for monitoring downtime while you try to solve a problem.
while true; do date; curl -IX GET '<URL>'; sleep 2; done;
