ился тарифный план с лучшими условиями и техподдержка без проблем сменила его по моей просьбе, сохранив все мои старые данные. Пинг до средней полосы России 50 мс, скорость загрузки упирается в предел моего домашнего провайдера ~100 мбит/сек.

ror: ERR_CONNECTION_RESET (Chrome) when loading more than ~30 photos per page. I lost on this error over 90 hours!! Nothing in app logs, nginx logs, anywhere... Seems like browser reset the connection, but after moving to a new server the error is gone and there is no problem with loading 200+ photos per page. Simply unreliable VPS provider seems to block too many file request (even in reasonable range). Also quite normal are some stalls. Page may not load for a couple of seconds. Or SSH connection may stall for random time - htop shows 90% free resource so again problem is with service provider. They offer very much but most of it is FAKE. Hmm also beware of testing with benchmarks. At first benchmark's results looked very promising but after about 1 month server tremendously slowed down.
