Hello Everyone,

Been trying to get a straight answer from telkom but no joy.

Quite a few of my international sites that I regularly visit are suddenly showing:

Bad Gateway
The following error occurred:

Code: 
 The IP address was not found during the DNS lookup. Contact your system administrator.
Please contact the administrator.

If I don't go through the transparent proxy things work just fine ....

Anyone else experience this ?

Eventually got feedback ...

JHB and PTA seem to be affected but but since Telkom are "testing" ... they've not put anything on the notice board or let the call centre staff know.

Hope it's fixed by 2morrow.
 
Go through a proxy in the interum.
I set one up through my hosting, but you can get access via free proxies if you don't have CGI-BIN access on a server.

If you do have cgi-bin access, CGIProxy works like a charm :-

Another thing you can try is a combo of Tor and Privoxy :-

Tor : - http://tor.eff.org/
Privoxy : - http://www.privoxy.org/

It results in fairly slow internet access, but at least you can get to places.
 
Testing huh howcome everyone using 196.25.255.34 and 196.25.255.3 cant access this forum, that really upsets me

Oh yeah, forgot to say, pretty obvious really :-

Don't use anonymous proxy servers stored on servers; aside from your own; for sensitive data. Pretty obvious, sure, but you never know.
Logging into a forum you visit on a regular basis when using a web anon proxy service is a baaaaad idea.

If you run it on your own server account, no prob.

When you login on ADSL SAIX/Telkom sets your DNS servers to 196.25.255.34 and 196.25.255.3. (I guess not allways the same depending on where you are). However I saw our router/firewall at work logging this afternoon that 196.25.255.34 was "refusing recursive name lookups". That means it will only reply if the domain is registered on that server, it wont query other name servers. So efectivly its going to say the domain does not exist. The way to fix this is to manualy set your own DNS server settings to 196.25.1.11 and/or 196.43.1.11 until they fix the problem.
Now if someone knows how to contact someone knowledgeable
at SAIX to tell them to fix 196.25.255.34, they better do so. Going via the usual support channels they will probably have you reinstalling Windows or something silly.
 
Quite correct asmith ... We use our own recursive dns servers locally ... problem was simply the transparent proxy server ALSO uses the dns servers ... ggrrr
