The magic switch for the Debconf wireless network is sharing its socket with a TV. When the TV is plugged in or unplugged, sometimes the switch's plug comes loose, and the whole wireless network goes down.
Our Internet connection is dependent on an antenna on the roof of the local Internet café that sometimes comes down in high wind, and which has a flaky power connection.
And now the route from the airport is blocked too. (Maybe not any more.. we don't know.)
On a more personal note, my laptop's power cable is now held together with insulating tape.
