The migration to a new server is finally done. everything should be a lot faster and more stable now.
Yesterday we completed the migration to a new main application server. The new machine has 8 cores, 16GB RAM, 1,5TB usabel harddisk space and unlimited traffic. Together with our other servers for mail, backup, static content, API requests and other small sister sites, this should be enough juice for a few more month of growth.
I´m very sorry for the stability and performance problems in the last few weeks.
