WTF? So help!

I am still not able to access blogspot.com or typepad.com. And a customer service executive at my ISP told me that they have not blocked any sites. She also suggested that I type in the IP address instead of the name, and when I did that, presto! There was Blogger in all its glory.

Trace complete.

So how the heck does this happen? Anyway typing in the IP is no big bother, but I am sick and tired of workarounds when the straight thing should work. I am fucking paying for it. How could this happen? Is the name server screwing up? What do I confront my ISP's customer service executive with, the next time I call?

Anand,
Both blogger.com & blogspot.com are hosted in the server with ip 66.102.15.100. If you visit blogspot.com you will be redirected to blogger.com. All the blogspot blogs are hosted in the server with ip 66.102.15.101. You will not be able to browse the blogspot.com blogs with the ip address.

1. ping the ip address 66.102.15.101 using ping66.102.15.101 command. If you are not able to reach the server then your ISP has blocked the ip address and as far as I know nothing can be done at your end to bypass. Your ISP has to resolve this.
2. If you are able to successfully ping 66.102.15.101 then try to execute this command nslookup mdeii.blogspot.com in the command prompt.

If you get something like this then everything is ok at your ISP's side and the problem is at your end.

C:\>nslookup mdeii.blogspot.com
Server: ******************
Address: ******************

Non-authoritative answer:
Name: blogspot.blogger.com
Address: 66.102.15.101
Aliases: mdeii.blogspot.com


If you get some out put like this then your ISP has blocked the blogspot.com thru their DNS servers.

C:\>nslookup mdeii.blogspot.com
Server: **********
Address: **********

*** ********** can't find mdeii.blogspot.com: Non-existent domain

This can be bypassed in two ways,
1. Add the following line to the end of the file c:\WINDOWS\system32\drivers\etc\hosts.

66.102.15.101 mdeii.blogspot.com

Now you shud be able to access mdeii.blogspot.com in the browser. You have to manually add all the blogspot address manually like this.
2. Bypass the ISP's DNS server and use someother DNS server like http://www.opendns.com/start/ . This involves changing the network settings. you may have to note down all the settings that you are changing while changing the DNS. If any problem happens you can go back to the old settings.

Hope this helps to resolve the problem. Let me know how it works. If you have any questions then shoot a mail to saravanannkl@gmail.com

Maybe you are suffering from the effects of what has been discussed quite a bit here... on BoingBoing

If indeed you can acccess by IP and just not by name, then that was a silly way to block blogspot indeed. Removing the name from DNS is so silly.

Here's a handy way to get past that annoyance. On a Windows machine, open up the file named "hosts" in c:\windows\system32\drivers\etc and add a line that specifies the name and IP address like so.

66.102.15.101 blogspot.com

Enjoy!

BSNL DataOne is working fine, but VSNL (what I have in the college campus) is still down... I should try this technique, but I wish that there was some way to introduce some kind of wildcard character into the hosts file, in order to view all blogspot blogs.

Update: VSNL is working fine now (at least for blogspot blogs)
