Hey folks,

Anyone else having the issue: Cloudflare DNS services on its primary ip address 1.1.1.1 is inaccessible. But their backup/secondary 1.0.0.1 is accessible

#1: https://1.1.1.1 is inaccessible



#2: Regular DNS lookup requests to 1.1.1.1 fails



#3: Encrypted DNS over TLS to 1.1.1.1 fails (what the heck is dns over tls?)



Note that, pinging 1.1.1.1 works fine, 1.1.1.1 is responding. Traceroute looks fine.



1.1.1.1 appears to be accessible from other ISPs. I tested DiGi was accessible. The issue has been persisting since sometime last week. Called fault reporting @ maxis helpdesk at 123 but the support staff could not understand the problem (He tried change my maxis router's dns to google dns in an attempt to fix the problem) and did not assign a case id; and asked that I email custermersupport@maxis.com.my instead to resolve my issue. Emailed them on 15th Oct 2019, today is the 17th 24 hours no response what so ever; no acknowledgement of receiving my email.

Cloudflare is a major content delivery network (CDN) their servers don't usually go down for such an extended period of time. Is this: ignorance, incompetence or worse: shenanigans on Maxis's part?

Yea i cant use 1.1.1.1 for testing yesterday. Good thing i run my own resolver

Same, tq for the info. Tested and valid that maxis is blocking them. Removing 1.1.1.1 and 1.0.0.1 from my DNS list

Subject matter update:

Maxis has finally acknowledged the issue today (after the MCMC report, last week) and has implemented a fix.

So far all looks its up and back
