Chch status
I live some 70km outside of Chch so just got a minor rattling.
Internet access will depend on ISP. I lost mine approx 30 min after the quake but it is back now.
Cell and texting were intermittent for a while but are now pretty much sorted.
There are several orders of magnitude of difference between Haiti and this Chch quake. Haiti had 200k+ people killed. Christchurch has had less than 100.
Unlike Haiti where comms was out for weeks, Christchurch comms are pretty much fully reestablished so people can check on each other via phone, texting etc.
The finder thing might have been useful for Haiti where this was the only link for many, but the conditions in Christchurch are completely different meaning it is unlikely to be of any real use.
