Yes, my 'desktop' machine is left turned on all the time and acts as a
server for the other machines (and devices) on our LAN.  I've put
dnsmasq on it to provide DNS and DHCP so that all machine/devices on
the network can be referred to by name without giving them static IP
addresses and putting them in /etc/hosts everywhere.  It's also a web
server for a few bits and pieces and has ssh access from the outside
world.

Note it's only one site that locks up usually, sites on other tabs in
the same browser continue to work fine.  I also have ssh to outside
sites which continues to work OK.
