Those small TelstraClear problems start to annoy me...

And obviously a few others (1, 2) agree there is a problem somewhere with TelstraClear network and services.

It actually looks like there is a few problems, not only one... 

To start the Paradise DNS seems to be out of sync a lot of times, and I've experienced errors trying to access some domains that are resolved correctly when using the Clear DNS - both Paradise and Clear DNS maintained by TelstraClear. I thought this could be something to do with the times, but I know of a couple of domains which are not updated on the Paradise DNS even after a couple of months.

Worse, if one tries to use something like OpenDNS then some of the IP returned are simply not accessible though TelstraClear. For example if you try to access Facebook when using OpenDNS and connected through the TelstraClear cable modem service then you will experience timeouts. It seems the IP returned by OpenDNS is not what TelstraClear expected to have when accessing tha domain and the whole page load just stalls with lots of timeouts.

Another problem is the following message that shows up sometimes for entire domains:

Network Error (tcp_error) The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.
It seems to indicate TelstraClear has a badly configured or badly performing transparent proxy. Sometimes just refreshing the request solves the problems, sometimes it happens multiple times during the day.

UPDATE: It appers other people have this problem with DNS also.

UPDATE: I have passed on some of the faults to a TelstraClear network engineer.
