Who's Using Symphony?

The system is relied upon in high-delivery environments by some of the world's most recognisable brands.

2 May 2013 Our migration to Rackspace Cloud: Recently, we've seen the Symphony site go offline in four separate occasions. For the past several years, the site has been hosted on Amazon's AWS. For the most part, the server environment had been very stable with only a handful of server hiccups all these years.

Four levels of commercial-grade support, available 24/7 from a team of Symphony specialists in UK, Australia, and the US. Learn more.
