Part of a wireless network in Brighton fell over this week after someone tied tinsel round an aerial. Volunteers at the community-based wifi network piertopier.net were baffled when one of their nodes located in Brighton hotel went AWOL.

When they went to investigate, they found tinsel wound round the aerial after festive hotel staff had run riot with Christmas decorations. Once the tinsel was removed, the network was back to its old self.
