Is ADSL down in Melbourne?

Post by plekme » Thu Mar 15, 2012 9:45 pm

At about 9:30pm tonight I seem to have lost connectivity to anything except Exetel forums, website and google. Is the internet down for anyone else?

I've cycled my modem and rebooted my computer with no avail.

Hi,

Currently there seems to be no known issues in the area at the moment, However I have cleared the connection from our end.

Therefore could you please recheck the service and let me know if you still unable to access the websites.

I've been looking at it the whole night and cycling my modem. Sometimes I get a connection to one site but then soon after it goes down. I always seem to be able to get to the exetel sites no problem though.

I've been looking at my ADSL modem diagnostics and it succeeds on testing the PPP connection, authenticating with ISP, and testing assigned IP address but then fails on pinging default gateway and pinging primary DNS server.

You can always try hardcoding your computer's DNS to test connectivity problems like this. That, or a NSLOOKUP command is often useful to find out if the issue is DNS based. However, failing the ping to default gateway...I wonder if this a symptom of a duplicate IP address or something? Check under your Member Facilities > Home > Network/Connection Problems (https://www.exetel.com.au/members/service_status.php) to see if a Duplicate IP comes up. Alternatively, it might just be that the default gateway is closed to pings.

To hardcode DNS: Network connections > right click Local area connection (or Wireless connection) > Properties > TCP/IP > Properties > Use the following DNS Server). I find Google's public DNS (8.8.8.8) easy to remember and has lookup / resolution speeds comparable to most local ISP DNS servers.

To use NSLOOKUP: In a command prompt window, try the command "NSLOOKUP http://www.google.com.au" and see if it resolves Google to it's IP address. Then try "NSLOOKUP http://www.google.com.au 8.8.8.8" to see if you can resolve the URL to its IP address using a hardcoded DNS server (in this case, Google's public DNS). If the later works and the former doesn't, then it is a DNS resolution problem and you will benefit from hardcoding the DNS Server to something like 8.8.8.8 (at least temporarily, though I have mine permanently set)

I went here and it says I dont have a duplicate IP.

I tried doing this with using the automatically assigned DNS as well as manually assigning it to 8.8.8.8 and I got timeouts in both cases when I did both NSLOOKUP commands (with the 8.8.8.8 and without).

Code: Select all

C:\Users\Pete>nslookup http://www.google.com.au
DNS request timed out.
    timeout was 2 seconds.
Server:  UnKnown
Address:  8.8.8.8

DNS request timed out.
    timeout was 2 seconds.

    timeout was 2 seconds.

    timeout was 2 seconds.

    timeout was 2 seconds.
*** Request to UnKnown timed-out
Finally, because I am worried that the storms last night may have had some part to play in this (fried the router?), I reset my router settings to factory default and just configured the basic settings so that this eliminated any chance I configured NAT or anything incorrectly but it still does not fix the issue. I also am testing on two different machines (PC and mobile) to make sure its not machine specific either.

just an update to what is happening now is that I get intermittent connectivity to websites. That is, I can sometimes get to common websites (I am trying Microsoft, The Age, XDA Developers, Whirlpool, SpeedTest) and I can get to them sometimes and sometimes I cant.

In all cases it takes > 1 minute to load. When the pages load its not a normal HTML page but a text based page.

When SpeedTest actually loaded I ran a test and I got my normal results (~7Mbps up) but the test took 3-4 minutes to complete.
