(emergency)Not resolving a certain domain

Hello this is an emergency request to solve a domain resolution problem at 1.1.1.1. I was trying to visit https://www.cdslindia.com but my browser was saying dns records not found for the site. I use tls://1.1.1.1 for dns resolutions.

This website is related to stock market transactions and it needs to be rectified immediately. Otherwise we have to change our dns provider on multiple devices

Hi @ayanchakraborty3199 thank you for the report. It appears to resolve fine for me. Can you please review Have problems with 1.1.1.1? *Read Me First* and provide additional detail if it remains an issue for you?

Hi @ayanchakraborty3199, I see this domain is resolving, do you still have any issue?

Yeah, it seems like the BOM server only has the issue and I can’t really select server so…

@system ur attention is requested

I use tls://1.1.1.1 for dns requests. I am connected to cloudfare bombay server. It can’t resolve cdslindia.com. Although users from servers located in different regions don’t have this issue. I have complained multiple times. No one cares

Hi @ayanchakraborty3199, the domain www.cdslindia.com delegate itself to several nameservers, among all the address, only 125.16.3.75 returns an answer. Others either return SERVFAIL or don’t respond at all.

Google and cloudfare dns both failed to resolve the domain. But my local ISP dns had resolved it correctly.

I wonder if the admin of the domain applied any network restriction, so only certain resolver is allowed. Maybe you want to contact on the other side to figure it out? We can investigate further as long as the name servers respond.

Thanks.

There is no such restriction that “only certain resolver is allowed” because if I use a vpn to other country and use 1.1 1.1 from that country the website is reachable. Could I make myself clear?
Also local dns servers that I wrote is not any perticular server. All Indian ISPs have their individual dns servers and all of them resolve correctly

My point is, it’s very likely the upstream name servers have blocked Cloudflare’s servers(and also Google’s) in BOM from accessing them. It’s beyond our control, sorry.

Ok, I have sent them a mail. But its a big corporation I wonder if it will have any effect. They company keeps demat accounts of thousands of people needed in stock market. They have a very nice website and all. I don’t know how come these bugs happen :thinking:
