The Malaysian ccTLD suffered an outage on 15 June that led to losing the “availability of access to MYNIC’s domain services” and all .my websites being offline for hours.
Explaining the problem, MYNIC said there was a “broken chain of trust between the servers in MYNIC and Internet Assigned Numbers Authority (IANA)”.
In a post on their Facebook page and Twitter account, MYNIC, the .my country code top level domain manager, said they “are currently experiencing some Technical Issue related to DNSSEC chain with IANA. We feel sorry for any inconvenience to the customers. We are working hard to resolve this issue as soon as possible.”
While some websites continued to be available during the outage, this was because of sites that had been cached around the world.
Explaining the problem, MYNIC said in a statement that their “technical team acted upon the report and are working together with Internet Assigned Numbers Authority (IANA) and Verisign to resolve the problem. As part of the resolution to the problem, MYNIC’s DNSSEC key was refreshed and pushed to IANA servers.”
The outage did not result in any breaches of customer data however there were criticisms it took MYNIC 10 hours to inform registrants of the problem.
Normal service resumed at 15:00 on 16 June Malaysian time but “the availability of some .my sites will take more time to be restored as DNS servers cycles its cache.”
