There's a lot of active gear introducing delays between those ends. Pinging www.govt.nz, which is about 17000km from me and as close to the antipode as I can find in a quick search, pings at around 300 to 400ms, so only at about 15 to 20% of c.

Huh. My nearest land antipode (from Boston, MA, USA) is Perth, and I get about 150ms ping to there. Regardless, even 400 ms is a far cry from 2000 ms.

A ping is a round trip, so you have to double the distance.
