By default, an IIS application pool (an “AppPool” hereinafter) recycles on a regular time interval of 1740 minutes, or 29 hours. One reason for this time interval is that application pool don’t recycle at the same moment every day (every day at 07.00 for example).

The connection is refused, and PHP has to fallback to IPv4. The fallback takes a significant amount of time. Too much time if you’d asked me. Unfortunately this fallback to IPv4 is still slow today…
