not sure ... was it the time I deleted the table space containing the unbanked transactions for a local council which was about £1 million (I did a very hasty recovery) or when i accidentally deleted the table space of the last 3 years data for another council ... which took 3 weeks to recover ... or when I setup an ISDN modem to dial the wrong number every 30 seconds for 6 months costing £10k after discount (the bill snapped the table legs when it was dropped) .....
