Hello, something happened in these days. I could always load the ssh shell in a while, today my site is serving images very late. (already flushed redis cache and verified that nginx is not under attack through nginx_status, normal numbers of requests), the vps node results fine too. So i noticed that it takes more than 10 sec before getting the ssh prompt. The machine has something wrong, any ideas? I have another vps that hosts the international site version (exactly same specs and config of the first one, even the site platform is same, just the language is english there) and the shell answers promptly. Thank you.
