I'm with Fyx also known as Maxnet/Vocus.
I cannot access http://www.wheedle.co.nz through Fyx. On Chrome I get "the connection to wheedle.co.nz was interrupted" and similar messages on other browsers and different machines.
I expect this will sort itself out soonish like most issues of this nature do. I will put in a support call next week sometime if it is still an issue.
In the meantime if someone knows the precise cause I would be interested to know that.
Thanks!
