Just checked with the client and he says he has tried the above 06 number, can get through to the PABX as you did, can get the network status message but its been the same message for the past 10 days indicating there is a problem and should be fixed by the end of the day. If you try to get through to Customer Services the line goes dead.
note: I've not tried contacting them personally, just going off the client's word
Apparently the owner's wife is crook and they have gone to Australia for treament. The company has been handed over to Thin Air to be 'looked after' except Thin Air are more concerned about getting customers off the Airstream network and on to Thin Air. Have also heard he owes a bit of money but that is just rumours. A client of mine wanted to buy the Airstream network but it all just sounded a bit dodgy to me.
If it were me I would be going to Inspire Net and not Thin Air. Inspire's network is built far better than Thin Air's and is much more stable. Throughput is better due to Inspire having far superior backhaul and you will get far better support from Inspire as they have a proper support team rather than the one tech that Thin Air have.
Edit: Does your client actually need service from a WISP or is there a fixed line service available? There has been quite bit of work done in Foxton recently and a lot of people on wireless networks are now in reach of ADSL.
That makes sense. The rumour I heard was that he owed about 10 months on his back haul.
The OP's client needs to jump ship. Inspire would be my choice if wireless is required.
Its a bit sad the owner let things just deteriorate. He had some good locations for sites just let things get on top of him. Sucks for his clients too! About 70-odd clients were still with him from what I heard last.
I have spoken to Geoff (owner of Airstream) a week ago and can confirm he is now living in Aust. and has a job with a School over there. I also had a number of his customers calling me asking for Wireless internet as their connections have been down for weeks.
I'm in the process of setting up another wireless link to my wireless broadband network up at Wharite to pick up greater coverage for this region. We'll be covering Palmerston North, Feilding, Sanson, Bulls plus rural. Site should be up and running in a few weeks.
