Well, that's more true in the UK market than in a lot of others: at
least there is choice. Look at the US for a worse example: monopolies
and duopolies everywhere, most dire.

esperi is me.

Obviously that 200ms was a spuriously high ping time from a busy router.

AAISP routers.

My ADSL router (but not firewall, that's one hop downstream).

300ms roundtrip is not bad -- it's about what you get from the protocol
overhead from an ordinary POTS modem. But still.

I'm not sure about that. I'm always on the edge of panic in such places.

Hey, I lived with a Netra in my bedroom for years and barely noticed the
jet-engine howl.

Likewise the clunking of people driving much too fast over the speed
bump they just put in outside my house.

Hey, a deeper hell is coming sooner. The Olympics.

I just got out in time.

Hey, there's lots of room for brand new infrastructure in Christchurch! 
(How do you think Japan always manages to be so near the bleeding edge? 
They rebuild everything every few decades!)

Whatever happened to Mercury Energy after the power cut incident? I know
that at the time there was discussion of the problems involved in giving
anyone involved any sort of fair trial (for incompetence or whatever),
because *everyone* has some connection to Auckland...

I hope Mercury Energy's directors didn't survive but I suspect they did.
What is a mere six months of blackout? You should have bought a bigger
generator! Perhaps they didn't get a bonus that year.
