The expiry date is not to confuse with drop date. Update date is just their system, usually updated when page loaded. I assume you used whois.com?
Try use the registry whois directly, and you'll see its dropping today.
I found a domain name for $5K that I am interested in. The domain name has a white screen of death and I can’t find it on any of the major market places. However GoDaddy listed it as for sale from a third-party and I’m thinking of buying it.
Does anyone have experience of buying domains listed...
