Poddery Migration

As you may all know we have been trying to move poddery.com to a new server since we had some bitter experiences with our current hosting provider scaleway.com. During the last two weeks we were continuously trying to get it done.

On March 23-24 some of us (@akhilvarkey, @bady, @balasankarchelamat, @harishk, @kannanvm, @mujeebcpy, @praveenarimbrathod, @ranjithsiji, @sgk and @srud4) gathered at thrissur to work on some of the issues listed here. During that meeting we ordered a new server from hetzner.com with the following specs for $28/month:
* Intel Xeon E3-1246V3 Processor
* 32GB DDR3 RAM
* 2x2TB HDD

(For details of the old server pls see wiki.fsci.org.in).

Currently we have done the following on the new server:
* Activated the server with Debian Stretch and upgraded it to Buster.
* Configured RAID and LVM on LUKS (for encrypted data partitions) with separate partitions for database, static files (such as user-uploaded files) and logs.
* Installed all necessary packages to run poddery services such as nginx, mysql, postgresql, diaspora, matrix-synapse, prosody, etc.
* Upgraded diaspora to v0.7.6 from v0.7.2.
* Installed matrix-synapse package from official debian repo instead of from upstream source.

What's left to do:
* Make the final switch (mainly synchronizing database & changing DNS configuration to point to the new server).
* Test all services. We will keep the old server as is until the new server is properly tested.
* Document everything in detail at wiki.fsci.org.in.

Tonight we're going to the make the switch and hence there'll be a downtime of all poddery services for a short period of time (hopefully less than 4 hours). We kindly request all of you to join with us for testing the services. If you find any issues please report here or in the poddery matrix room.
