I still remember the first day I bought domains for traffic. Back then I had just a clutch of names but when I finally had the light-bulb moment and got the model, I ran out and registered 1000 of the best traffic names I could find unreg'd.. I had my web-host activate them and bam, the traffic started flowing. It was a Tuesday.. I remember thinking "Wow.. wait till the weekend when all these folks are home and have time to surf the web!"
Boy was I naive. Nobody surfs the Web on the weekend. Monday is the biggest traffic day for most domainers because Monday is a working day and the majority of the Internet population surfs at work. Apparently I was too conscientious an employee. I actually worked at work.
You can see the AM rush as North America comes online and millions of people fire up their browsers. My busiest hours are between 10 and noon in the North American timezones.. Up to 20 visits a second for hours on end. It's cool. Midnight sucks.. we get about 7 visits a second during the witching hour.
I have been seeing a smoothing of the band over recent years. On a relative percentage basis, the MRTG spikes are not as pronounced as they used to be. These mounds used to look a lot more like pine trees. I think we'll live to see the day when they look like speed-bumps, as people are online pretty much all the time..
