I've noticed in the log of the new Sky Hub that once or twice, every so often, is says "No lease renewal received".

I'm on MER and it normally renews the lease every 30 mins.

Whenever it's said "No lease renewal received" it's renewed the lease fine on the next attempt. Also, the connection doesn't appear to have dropped.

Just wanted to know if it's anything I should be worried about or if it's a normal thing? Would it be related to my end (the hub) or Sky's end (their equipment)?
