I got an email from ORCSWEB, my most excellent hosting company (check them out) that I'd used over 230 GIGs of bandwidth for the month. Oy. First, I was happy that the site is doing well, then I was disturbed. Something MUST be wrong.
So, I asked them to hook me up with a better stats package than the default and they hooked up SmarterStats immediately. I checked it out:
Notice anything odd there? Yes, my favicon.ico used 27 GIGS of bandwidth in the month. Yikes.
Turns out my icon was 70k, as I made it a wonderful high-quality "Vista" icon in an attempt to make things pleasant and everything for folks. Of course, I didn't noticed when it was taking up over 11% of my monthly bandwidth.
Long story short, I changed my icon from a multi-resolution (6 resolutions, all 16M colors) to a simpler one using Junior Icon Editor that has 3 resolutions at 16 colors and still looks nice. The icon is now under 4k, a 95% reduction that should lower this month's bandwidth by 25 GIGS.
