Survival Server Health
Over the last 3-4 days, I have noticed that from around 23:00GMT onwards the survival server's 'health' appears to drastically reduce, giving players an increase in block and normal lag.
It was confirmed by other players over the last few days as well, including those in different timezones/continents to me, which leads me to believe it may be a server issue, and nothing to do with my client/connection.

You'll never see a church with free Wi-Fi, guess they don't want to compete with an invisible power that actually works.
