Off power
Nearby, the power line to our block has been extended – years ago – but as was discovered today, it was badly done, in time, the isolating layers deteriated and this morning, about 11:00, the circuits were shortcut and a neighbouring block was powerless. As a result, our block was switched off power at about 12:30, and it lasted until 18:30 that power was restored.
All equipment in the attic had to be swithed off: if kept on the grid, it’s sudden consumption creates a peak that exceeds the capacity of the fuse so it will blow (Well, we’ve got “automatic” fuses – they simply turn power off that particular line, and it is very easy to re-enable it.). After that, firest the disks were made alive again, then the Alpha. No problem at all, this time. Just that the clock was 5 minutes late.
