This month I finish my university career and along with this move I sadly will stop working at Insanity Radio, the student (now community) radio station I’ve been running tech at for about 3 years now. Needless to say, I’m going to miss the place and the people, and the challenges that came with that environment.
Specifically: No budget (a total of £3,000 income annually, compared to the average income of £75,000 for most Community Radio stations according to Ofcom). No paid full-time staff. And a desire for 100% availability regardless.
Over the years the systems at Insanity have evolved and grown – they started out as a single computer for playout, a single encoder and streaming server running Windows Media Encoder with about 50% availability best-case, and we’re now deploying high availability clusters for streaming and encoding, have very few single points of failure, with a total of 21 computers. Back in 2009 we had significant amounts of dead air – outside of a processor failure we’ve had very few incidents since 2011.
Building systems for reliability on no money is a tricky thing to do, and it’s even harder when the people maintaining the infrastructure change on a potentially annual basis. This post is basically a quick encapsulation of some of the most important things to focus on to make such a situation work – not just from a technological perspective but from a human perspective too.
