503 Service Unavailable

Got this in debug.log:

file_get_contents(https://www.quic.cloud/ips): failed to open stream: HTTP request failed! HTTP/1.0 503 Service Unavailable
 in /plugins/pareto-security/pareto_functions.php on line 2196

Looking at line 2196, it can be seen that’s indeed trying to resolve https://www.quic.cloud/ips via file_get_contents(), which is indeed returning a 503 error atm.

However, file_get_contents() is a blocking function that may degrade performance in situations like the above. Here’s a php script, for example, that calls a urls without blocking and returns immediately.
