When do domains get suspended?

[Hashim]

A domain name that I really like is due to expire, and 7 different drop catching/backordering sites say that it can't be booked because it's currently suspended. Do domains become suspended the moment they expire, or is there a specific amount of time after that that they don't?

Thank you.

google "uk domain drop cycle" or something similar. It will get you loads of results
