We had a power supply failure on the main server this morning. The power supply was replaced and the server was up and running within an hour or so. Although the server works fine now we will replace it with newer and more powerful hardware within the next few days, a test migration is progress.

New server hardware will be:

Intel Core i7-7700
64 GB DDR4 RAM
2 x 512 GB NVMe SSD in RAID 1
1 Gbit/s connection

The SSD's should improve performance by quite a bit.

The secondary server which stores automatic daily backups and also host some sites will keep its current hardware (i7-4770, 32 GB RAM, 2 x 2 TB SATA in RAID 0) for now.
