Easter means today is a holiday in much of the Reg-reading world, but that won't stop us from delivering another instalment of On Call - the reader contributed column that shares your tech support stories. To mark the occasion, The Register has revisited our mailbag of holiday-adjacent stories to tell the tale of a reader we'll Regomize as "Marcus," who told us he worked as a contractor for a "very large, very blue, blue-chip company" in the Netherlands and helped it prepare for Y2K.
