Redis 官网 昨日罕见地宕机了一段时间。宕机原本不是什么新鲜事，但戏剧性的是网站的报错信息居然是连接不上 Redis。
redis::cannotconnecterror at / error connecting to redis on 127.0.0.1:6379 (errno::econnrefused)

However lately I installed there. And apparently it does not garbage collect the session keys well enough or something like that. So memory accumulated and the instance quit for OOM, but this probably only happened because the instance is very low on mem.
TLDR, today I'm going to resize it to a 4GB instance for 20$/month. Looks like a good upgrade :-D Maybe the site will be faster too, even if it was quite fast actually, already. Lessons: if you use Redis as your store, you can do a lot with very little.

Today went down for some time, sorry about this problem, is running in a $5 / month droplet at. I was a bit too cheap on that :-) But since it uses Redis as its main store + a Ruby app, this was enough.
