 +docwho is tried of all the fucks at the space bellyaching about "OMG the network sucks" when 98/100 times the problem is with the observer and their ability to understand what is actually wrong with the network at the space. Sometimes the spaces 2.4GHz RF spectrum gets demolished by peoples projects inadvertently. Other times it could be round-robin DSL load balancing causing the issue. Still other times people just wanna bitch about something. This sign is so that when people bitch about the network, they can be told to look at the sign and see if there actually is a problem or not.
