Much to my dismay, the next day, the expiration date showed that it was renewed, as in the expiration date was now a year from now.
Then yesterday, I recieved notice that the staus of the domain had changed. That the expiration date had gone back to the expiration of a few weeks ago (and to my delight is now in redemption period).
How can this happen? Or is it normal and I am so not paying attention that I just had not seen it before?
2 possibilities:
1. The registrar asked the Registry to delete it soon after autorenewing it. I found one registrar whose grace period is between 1-5 days, while another's is 0.
2. The domain name might have been autorenewed by the registrar, but its registrant "politely requested" deletion of it because s/he didn't want it anymore.
Oh well, at least it's on RGP like you say. You know what to do next. :)
