I just tried to tell my dad what I'd achieved today, and had one of those "first create the universe" moments. I pretty much ended up describing (simplified) the whole technical history of my hosting network, what BGP, OSPF and VRRP do and how they fit together, how my router setup has evolved over time, and quite a few sidetracks too, to explain that what I'd done today was to complete a script that sets up Linux "virtual MAC interfaces" for the VRRP implementation I'm hoping to soon migrate to, because the vrrp keyword built into the ifupdown2 package I've been using doesn't do a few things quite exactly the way I need and it's easier to reimplement than to fix.

Explaining all that took probably an hour and left my throat really dry and with the realisation of just how *much* technical stuff I have to look after to run a whole hosting ISP single-handedly. I really *really* ought to actually try to get some more customers in - pretty much all the customers I have, I got by accident.

FYI I do server colocation in London, UK, plus most of the other stuff a hoster does: domains and DNS, email (well, not really at the moment, email's one of the more horrible things to host and the current setup is very old and crusty and needs modernising before I'll be happy taking on email customers), web hosting, virtual servers, etc. My main selling points are service and reliability - if cost is your main factor in choosing a host, you might want to try elsewhere. ;) If I haven't scared you off and you're interested, feel free to ask.
