This brought on a thousand yard stare for a moment. ;) Besides my experience of 
various ordinary failures over the last 30 years, my Internet connection in the 
last 2 weeks has been a disaster!

But then I realised Plan 9 expects reliability and it's not really so bad. If 
you know the network will be unreliable, you tunnel connections over `aan` 
(always available network). Provided the server IP address doesn't change, aan 
can reconnect after failures.
