New Scientist in conjunction with Researchers at the International Computer Science Institute (ICSI) in Berkeley, California have built a tool to see what types of internet traffic are being "interfered with" by your ISP.

http://www.newscientist.com/article/dn18938-revealing-the-secrets-of-the-internets-gatekeepers.html

You can run the test here:

http://netalyzr.icsi.berkeley.edu/index.html

It will be interesting to see how New Zealand ISPs fare.

Here are my results for Vodafone redzone network in Auckland.

Telecom Pro, An interesting test

Minor Aberrations

* Certain TCP protocols are blocked in outbound traffic
* Network packet buffering may be excessive

Direct TCP access to remote SMTP servers (port 25) succeeds, but does not return the expected content.

This suggests that your network enforces a mandatory SMTP proxy which may or may not allow you to send email directly from your system. This is probably a countermeasure against malware abusing infected machines for generating spam. You ISP also likely provides a specific mail server that is permitted. Also, webmail services remain unaffected.

The applet received an empty response instead of our normal banner. This suggests that a firewall, proxy, or filter initially allowed the connection and then terminated it, either because it did not understand our server's reply or decided to block the service.

Major:

Direct TCP connections to remote authenticated SMTP servers (port 587) succeed, but do not receive the expected content.

The applet received the following reply instead of our expected header:
"421 Cannot establish SSL with SMTP server 174.129.176.88:465, SSL_connect error 336031996 "

We estimate your downlink as having 2100 msec of buffering. This is quite high, and you may experience substantial disruption to your network performance when performing interactive tasks such as web-surfing while simultaneously conducting large downloads. With such a buffer, real-time applications such as games or audio chat can work quite poorly when conducting large downloads at the same time.

CraZeD,

I'm on Telecom Big Time as well.

Based on the results I have, it would suggest that 1080p's blocked ports would be due to router setup or an internal firewall. I'm currently using a 3Com router and I found that disabling the url filter this resulted in a faster initial response time as well.

On a Slingshot "everyday" plan with proxy disabled and interleaving off.

Minor Aberrations

Network bandwidth may be low

Network packet buffering may be excessive

We received unexpected and possibly dangerous results when looking up important names

Your computer's clock is slightly fast

Network bandwidth measurements: Upload 140 Kbit/sec, Download 390 Kbit/sec
Your Uplink: We measured your uplink's sending bandwidth at 140 Kbit/sec. This rate could be considered somewhat slow, and may affect your user experience if you perform large transfers.
Your Downlink: We measured your downlink's receiving bandwidth at 390 Kbit/sec. This rate could be considered somewhat slow, and may affect your user experience if you perform large transfers.
The modem syncs at ~5.5Mbps/160k, and no other network activity was present.

Network buffer measurements: Uplink 3500 ms, Downlink 310 ms
We estimate your uplink as having 3500 msec of buffering. This is quite high, and you may experience substantial disruption to your network performance when performing interactive tasks such as web-surfing while simultaneously conducting large uploads. With such a buffer, real-time applications such as games or audio chat can work quite poorly when conducting large uploads at the same time.
We estimate your downlink as having 310 msec of buffering. This level may serve well for maximizing speed while minimizing the impact of large transfers on other traffic.

DNS lookups of popular domains: Warning

1 popular name has a moderate anomaly: we are unable to find a reverse name associated with the IP address provided by your ISP's DNS server, although we expected to find a name. This is most likely due to a slow responding DNS server. If you rerun Netalyzr and see this condition remain, it could be due to a misconfiguration on the part of the domain owner or your DNS server could be misconfigured or enabling a Man-in-the-Middle attack.
