This is a problem with all sites, I can ssh into machines at will; also my weather updates fine (using the weather icon) and so does ntpd. -Lane
echo 0 > /proc/sys/net/ipv4/tcp_ecn
and I am sure your internet connection will work immediately.
Add to /etc/sysctl.conf
# Setting ECN off net.ipv4.tcp_ecn = 0
and run "sysctl -p" to activate that setting permanent.
--> this did not work.
