Whois throttling returns to bite Go Daddy on the ass

Go Daddy has been accused by a competitor of “thwarting” domain name transfers in violation of ICANN rules. (Note: story has been updated, see below).

The problem has reared its head due to the ongoing SOPA-related boycott of the company’s services, and appears to be related to Go Daddy’s decision earlier this year to throttle Whois queries.

NameCheap, one of the registrars that has been offering discounts to Go Daddy customers outraged by its recently recanted support of the controversial Stop Online Piracy Act, blogged today:

As many customers have recently complained of transfer issues, we suspect that this competitor [Go Daddy] is thwarting efforts to transfer domains away from them.

Specifically, GoDaddy appears to be returning incomplete WHOIS information to Namecheap, delaying the transfer process. This practice is against ICANN rules.

We at Namecheap believe that this action speaks volumes about the impact that informed customers are having on GoDaddy’s business.

It’s a shame that GoDaddy feels they have to block their (former) customers from voting with their dollars. We can only guess that at GoDaddy, desperate times call for desperate measures.

Part of transferring a domain from Go Daddy to NameCheap involves checking the identity of the registrant against Whois records.

Judging by a number of complaints made by Reddit readers today, it appears that NameCheap and other registrars are attempting to automatically query Go Daddy’s Whois database on port 43 at sufficient volume to trigger whatever throttling algorithm Go Daddy has in place to prevent the “harvesting” of contact data.

Go Daddy caused a similar ruckus earlier this year when it started blocking DomainTools and other Whois aggregation services from collecting full Whois records.

The registrar giant claimed then that it was trying to protect its customers by preventing the inappropriate use of their contact data.

However, while blocking a third-party information tool is merely annoying and disturbing, interfering with legitimate inter-registrar transfers could get Go Daddy into hot water, even if it is inadvertent.

NameCheap says it is doing the required Whois look-ups manually for now, and that it will honor each transfer request.

Giving Go Daddy the benefit of the doubt, I assume that this problem is ongoing largely due to the Christmas holiday, and that it will be rectified as soon as the appropriate people become aware of it.

Add this to your list of reasons .com and .net need a thick Whois.

UPDATE: All registrars have access to an ICANN service called RADAR, which enables them to specify the IP addresses they use to query competitors’ Whois databases.

Whitelisting IP addresses in this way could prevent a registrar’s queries being throttled, but not all registrars use the service.

According to this screenshot, NameCheap has not whitelisted any IP addresses in RADAR, which may be the reason it is having problems transferring Go Daddy customers’ domains to itself.
