I will ask the hosting company to start the DB upgrade process tomorrow morning. This means the DB will go offline 29-Oct-2015, probably after 1100Z. It will be offline for some hours as the files and DB is transferred to newer servers. On top of this there will be some DNS changes. DNS changes take time to filter across the internet. There is nothing that can be done to speed this up, we all have to wait, including me.
I would have liked to give everyone more notice but we need to get things fixed and rather than wait longer I feel it is better to get on with the changes as soon as possible.
#You should expect the DB to be unavailable for probably 4 to 24 hours.
