So our company is on 2degrees fibre for business for about 1 year and all has been running great, always online.

This is the first problem we have experienced and in talking to various tech support people at 2degrees and other internet providers as well as IRD themselves, we are not getting very far in resolving our problem.

Problem

When any computer or device tries to access the MyIR login area (https://services.ird.govt.nz) it won't load the login page at all. 

Steps to try and fix the issue so far...

 

1. We have tried all different types of browsers, cleared cookies, caches and flushdns (not fixed)
2. We run with an SBS Windows server domain and out gateway is usually set to the local IP of the server. So we conected straight to the modem as used that as the gateway (not fixed)
3. We then called IRD to see if they were blocking our static IP address (203.86.206.44). They said they don't block IP address at all. (not fixed)
4. We called 2degrees and they said that the tracert from our network to "services.ird.govt.nz" was getting aborted when it reached sparkdigital.co.nz (Spark). It seems sparkdigital host the IRD websites. Sparkdigital suggested we change our static IP address to resolve the issue (possible a big job though). Not going to do that yet until I understand what the cause of the issue is. (not tried yet)
5. We called sparkdigital.co.nz and talked to their technical support team in web services. They said they don't block IP addresses, but they could not explain why the timeout would occur at their server. (not fixed)
6. The only other thing I can think of is our router has been hacked or that our IP is on a blacklist and IRD/sparkdigital are blocking it unknowingly (not looked yet)

Please, if anyone has experience on at least where to look or what to check, we would be very grateful. Tracert below.

Thanks,
Dan
