It amazes me when I look back on my web career. My first website was hosted on an IP address - I'd literally tell people to visit h t t p : / / eight one dot ... - because I'd not come across DNS or how to use domains yet, never mind afford one when I figured them out I distinctly remember I could never seem to manage to make a website fast. It was always quick (total load time <10s) but it was never fast (<3s). I spent so long learning underlying systems and various caching options. 20 years later I can throw together anycast DNS, geo-routing, web/SQL cluster, in/out MX services, memcached cluster, load balancer, whatever you need. No bother. I'm glad that first site gave me so much grief!
