In my experience with unbound, it tends to return expired records in the hope that they are still valid, causing issues with services hosted in the cloud, where IP addresses rotate regularly. What I did was update the serve-expired-ttl setting in unbound’s configuration to 3 hours (down from the default 24h)

Ah, good idea! I just don’t have any non-magnetic screwdriver at home, I’m afraid as to what might happen if I get its magnetic tip close to a drive.

Oh wait, I found a lousy screwdriver, it works like a charm! It’s definitely the bottom one. Thank you very much!

FIY, the Minister’s party (Labour) is currently pushing a law to increase tenants’ rights, including preventing this exact situation from happening, which makes the whole situation even more ridiculous and hypocritical.

Labour’s Renters’ Rights Bill, which will become law next year, prohibits landlords who have ended a tenancy in order to sell a property from relisting it for higher rent until at least six months after tenants have moved out.
