FreeBSD used for Internet Infrastructure
- BSD has existed since the last 1970's and was the testbed
and reference implementation for TCP/IP.
- The Internet Software Consortium (ISC) uses FreeBSD
exclusively for f-root domain servers (in 21 cities now,
usually with 3 servers per city).
- Modern FreeBSD is extremely refined and
mature.
- FreeBSD consistently placed at the top of the "uptime"
lists produced by Netcraft to measure the stability of the
world's busiest websites.
