Sorry, but what are you doing in a lab that requires 13 year old router OS versions?

Hi NANOG,

in the past there was the Netcraft website which showed publicly "Servers with the highest uptime". Sadly that site 
apparently doesn't exist anymore.

I'm wondering what are the routers worldwide with the highest uptime. :)

I'll make a start. 2x Juniper M7i lab routers running BGP + VRRP:

Is that good or "like nothing"? :)
