Hi team,

I've been struggling to connect to docs.fedoraproject.org intermittently for a while, and finally investigated a little today.

The problem appears to be caused by a timeout of connections to one specific IP in your CDN, namely 13.244.113.71. It consistently times out, as demonstrated by this quick test, which I have run numerous times:

$ dig +short docs.fedoraproject.org|grep '^[1-9]' | while read ip; do  curl --resolve docs.fedoraproject.org:443:$ip --connect-timeout 30 https://docs.fedoraproject.org/en-US/docs/ --head --silent > /dev/null; echo $ip $?; done
38.145.60.20 0
38.145.60.21 0
13.244.113.71 28
8.43.85.67 0
13.245.77.95 0
8.43.85.73 0

I'm located in Mauritius, and have tested this from 3 different IPs, namely 102.222.106.243, 102.222.106.234 and 102.117.85.234, and they all produce the same results.

Kindly help me get to the bottom of this.

Thanks in advance.

Clifford
