Update as of 24-MAY-2016: Thanks to everybody for support – we’re back at 2 GB!
Due to a sorry state of my budget constraints for DNSCrypt and close to non-existing donations and paypal shutting down, I’ve decided to lower to the memory from 2GB to 1GB on the VM. This will cause lower cache hit ratio, but still allow to operate while achieving 43% lower monthly cost. Sorry :-(
