An organisation was doing their annual generator load test, when this happened:

It appears our upsteam ADSL telco has had a failure of an Ethernet switch. This has dropped ALL adsl circuits in Victora. (sic)

Just under an hour later it became obvious why:

It appears that the switch in question had not been connected to the essential power circuit. The telco’s switch had its power restored when the generator test was completed. We will working with the telco to get the switch transferred from mains to essential power on Monday.

Their summary of the testing:

Besides losing all ADSL in Victora, the generator power test went fine. (sic)

Oddly enough I didn’t notice anything that day with our home ADSL, so somebody likes me..
