Out of curiousity...I wonder if anyone has an idea of how many centos installations are out there? _______________________________________________

169,788 distinct IP addresses have asked for updates since 04-Mar-2005 from mirror.centos.org

That doesn't include anyone who does their updates from one of the external public mirrors (current 45 listed).

Hi,

I'm glad, nobody started to count directly, like "one" (me) :-) Apart from that I don't think, it's a good measure to count the IP addresses "since". A better measure might be to release _one_ update and to count, how many guys download that update within say two weeks, morover to ask the mirror guys to give away their access data for this update. The best way might be to implant an easter egg, which connects to a kind of a counter server, but this might lead to many discussions... cu - Michael

There's a couple of flaws with a "distinct IP" count:

1. Not all servers get updated (I know of 3 or 4 CentOS servers that probably haven't been updated in months. 2. One machine can get multiple IPs 3. Many machines can look line one IP

However, distinct IP does give us a rough estimate of installs. And even if it's off by 30% one way or another - it's a bigger number than I thought.

Just some other numbers to look at:

Bittorrent ISOs downloaded in 2 months: 32778 (that doesn't include any ISOs downloaded from external mirrors)

CentOS.org website traffic rating at alexa.com: 36,829 (that is better than several big name distros like Knoppix, Slackware, Xandros, Mepis, PCLinuxOnline, etc.)

Average traffic out of CentOS mirrors is 16.5 TB per Month.

(That is also only the CentOS.org mirrors ... not any traffic out of the close to 50 external public mirrors)
