On 24.04.20 at 06:00 by Europe/Helsinki our app hosted on Heroku in Ireland was totally not available for almost half an hour. In app logs I saw “ETIMEOUT 126.96.36.199:443”.
Seems it might be related to this case https://prnt.sc/s513my
It’s not the first time, we had such issues before.
Also yesterday uptime.bot notified us that our app was not available however this time I did not find any errors in logs, but only many “Client Request Interrupted” and slower requests than usual.
- Why these issues might happen and maybe you can recommend some ways of fixing them?
- Is there a possibility to make Cloudflare proxy work more stable or its better to disable it at all, but how to protect app then?
- Why when proxy is enabled all dns requests are going to server in USA (e. g . 188.8.131.52) if Cloudflare has other servers more clear to our server in Ireland?
