We took our eye off the ball for a few months and we were all celebrating our great growth month-over-month when yesterday I received an email from our Data Center. We were consuming more bandwith than what was allocated on our package. Our costs are going up.
Here is our monthly transfer total for the last 6 months:
- April: 72 GB
- May: 106 GB
- June: 118 GB
- July: 131 GB
- August: 197 GB
- September: 141 GB
- October: 165 GB (est.)
There is a strong correlation between data transfer and page views, although, it's not perfect because small changes on the system can cause step-functions on the amount of data transfer.
If you look close at the data you'll see that in September we had a drop of 28% in total transfer despite the fact that we served more page views. The primary reason is because we enabled HTTP Compression. If we hadn't done that, our transfer rate would be about 300% for October to what it was in April.
But the reason we enabled HTTP Compression was primarily to provide our users with faster downloads when using our service, the bandwith reduction is just a bonus for us.
