Why does the domain release date change at the nic.ru auction?

Question

Domain name market

Good afternoon.
On nic.ru, in the list of free domains, I found the one I needed.
It was on the 11th. According to whois - free-date: 2018-03-12 , also when ordering, nic.ru wrote that "may be free: 03/12/2018"
I paid and forgot.
Then on the 13th I decided to take a look, and nic.ru already writes: "may be released: 03/13/2018" , according to whois free-date, everything remained the same 2018-03-12.
On March 14, respectively, the text changed to "may be released: 03/14/2018" free-date is also unchanged. Today the same picture: +1 day :)
Do not tell me what this behavior depends on? And what is this magical "may be released"?
Thanks to.

Answer 1

Domains are deleted on the second working day after weekends and holidays until the end of the working week. Usually, this is from Tuesday to Friday inclusive. Therefore, if a domain is scheduled for deletion on Sunday, it is likely that it will be deleted on Tuesday or Wednesday.
If there are many domains to delete, no more than 25,000 domains per day will be deleted in each registry (15,000 in .RU and 10,000 in .РФ). Thus, after weekends or long holidays, deletion can be postponed for several days or weeks in a row.
When the deletion date is postponed, the date in whois and the registration service for vacant domains does not change. This is a technical feature of the registry.
Information about deleting a specific domain appears at approximately 12:10 Moscow time. The domain receives a special pendingDelete status, which means that the domain is unambiguously deleted at 17:00 Moscow time on the same day. If the status does not appear, then the domain will not be deleted.

Because the rucenter very often seeks to cheat :) especially if the domain is at least a pretty penny popular and it can be sold at auction, and not given away "just like that"
