I suspect a possible DNS issue. If it's what I suspect, then here's what happens...
Your computer asks its primary DNS server for the address matching cbr1100xx.org. DNS1 doesn't reply. Computer times out, asks DNS two. It may reply or time out, causing more delay. I'm going to go streamline the DNS settings. They often take many hours, up to 24, to take effect. Let me know what you see tomorrow.
It may affect different people in different ways because of how their ISP caches and looks up DNS.
