DNS issue causing CRON jobs to fail because of timeout

We were using OpenDNS instead of GoogleDNS on our Digital Ocean Server. Looks like some outrage in the DNS in Google and OpenDNS is causing the following time out erros

NoMethodError: undefined method `fb_error_code' for #<Faraday::ConnectionFailed>

I have changed the following configuration

# /etc/resolv.conf 
nameserver 208.67.222.222 
nameserver 208.67.220.220

and

# /etc/network/interfaces
dns-nameservers 208.67.222.222 208.67.220.220

and rebooted the system. But The sidekiq which used to normally take 1-2 min is not taking over 20mins to complete and throwing a lot of errors.

Hi @harshamv
Don’t use a single provider. Mix them. And remember to also include the IPv6 if you have activated that on your droplet.
I usually use Google, Hurricane Electric and Level3, but pick the ones you trust in:
