I told you so Exetel.

I use exetel for a number of services in Sydney.

I have always found them to be the cheapest, even if their ability to support their service is sub-optimal.

An example is right now, they are currently totally offline.

dig: couldn't get address for 'ns2.exetel.com.au': not found

This is something I reported (ticket #853640) to them around Oct 2008 (when they last had a failure), that the auDA has no in-balliwick glue for their DNS. I was told by their support supervisor, Dylan Friedewald, via email:

The DNS for helpdesk.exetel.com.au is operational and valid, I do not see the point in discussing that further.

It is interesting to note that Steve Waddington has blogged many times about customers being unable to identify issues, but it is even more interesting that when a customer does – it is explicitly denied as being a problem and then ignored.

Apart from no in-ballwick DNS glue, their nameservers are also open recursive ones. Great if you would like to perform a DoS attack against some unsuspecting person.

I have raised other issues with them that warrant further investigation and corrective action, lest they affect all their customers. But I no longer have the time to continually ping them about things.
