Internet services not to be affected as DNS servers undergo update

Internet services across the country are unlikely to be impacted over the next 48 hours even as the Domain Name System (DNS) servers undergo a security update coordinated by global regulator, Internet Corporation of Assigned Names and Numbers (ICANN).

“ICANN, the global certifying authority for DNS security, had taken a decision a year back to change the Trust Key. All ISPs were notified to update their configuration to the new key. Accordingly, the Internet Service Providers (ISP) have confirmed that they have already updated their DNS servers with the new key and the country does not carry any risk of impact on Internet services,” said National Cyber Security Coordinator Gulshan Rai in a statement on Friday. DNS servers are like the phone book for the Internet which translates human-friendly computer labels into their respective IP addresses. If the DNS servers become inactive, it will be impossible for users to access different websites in the absence of this translation.

The ICANN’s ongoing maintenance work over the next two days is to change the cryptographic key that helps protect DNS. This has been necessitated to counter the rising incidents of cyber attacks, ICANN said.

Rai had held a meeting with all ISPs in this regard on September 5. During which ISPs said that they had taken all necessary steps to update their systems in order to avoid any inconvenience to their users. Rai reviewed the situation again on Friday.

Sunil Abraham, founder, Centre for Internet and Society, said, “This security update is the responsibility of the management and network administrators at ISPs and telcos. Only time will tell what percentage of people have done their job. Its very likely that this number is very small, in case of people who haven’t updated their servers,” he explained.
