The Internet Corporation for Assigned Names and Numbers (ICANN) has selected three emergency back-end registry operators to guarantee domain names within a new generic top-level domain (gTLD) will resolve in the event of a failure at a new TLD operator, it said on Tuesday.

Emergency back-end registry operators, or EBEROs, are activated if a registry operator fails to provide or is unable to sustain five critical registry functions temporarily, or in the case of transition from one registry operator to another, ICANN said. "Having them in different regions of the world reduces the chance that a natural disaster would affect all three at any one time," it added.
ICANN's announcement closely follows criticism of its gTLD rollout plans. The pace of the rollout is too fast and could cause risks to the security and stability of the DNS (Domain Name System) and affect the working of the whole Internet, VeriSign has warned in a report outlining new gTLD security and stability issues, sent to ICANN and filed with the U.S. Securities and Exchange Commission (SEC) last week.
Concerns were also raised by PayPal and the Association of National Advertisers (ANA), a trade group.
The VeriSign report included criticism on the slow selection process of EBERO providers.
"ICANN's original plan was to select EBERO providers in June 2012 with simulations and drills in January and February 2013 and providers prepared to be live in March," VeriSign noted in its report. At the time the report was filed, there were no signed and tested EBERO providers, it said.
"With no EBERO providers, the continuity risk of any registry failure is significantly increased," VeriSign said. Allotted EBERO providers need six months from selection to preparation for testing. "Therefore, it is reasonable to conclude that from the date EBERO providers are selected that ICANN should expect that they will require six months to prepare for testing with another two months of testing prior to being prepared for a registry failure," VeriSign said.
If any registry should launch before the EBERO provider is ready to function as a back-up for gTLD domains, the continuity of operations risk could be measured in days, weeks, or even months, rather than the hours specified in the EBERO service level requirements in case of a registry failure or outage, VeriSign said.
