Problem with Wordpress updater and Jetpack connection (register_http_request_failed)

Question

Three days ago I uploaded new version of my blog, and when I was activate Jetpack plugin on Wordpress API, I always receive a message about http_headers. Below, the message that I’m getting:

Jetpack could not contact WordPress.com: register_http_request_failed. This usually means something is incorrectly configured on your web host.
name lookup timed out

I don’t change any configurations in my droplet, iptables or file permissions…yesterday (10/16/2014) I received a mail from Digital Ocean talking about SSL v3, and I think this can be the root of problem (or not).

Is there any change or lock on datacenter that could block Wordpress authentication with Wordpress API ?

More info

-Admin interface is so slow because wordpress always checks for updates of his core (5-10 seconds to get response for a request avg).

I found the problem on my DNS config. Here (in Brazil) we always use Google’s DNS (8.8.8.8 or 8.8.4.4), my droplet has these ones on resolv.conf.

I looking for NY public DNS and replaced current DNSs by this new one (66.93.87.2).

My /etc/resolv.conf:

#nameserver 4.2.2.2
#nameserver 8.8.8.8

nameserver 66.93.87.2

All internal requests from Wordpress are working perfectly.

I just found this answer (read the comment to the answer by davidkomer).

Only having one nameserver in resolv.conf fixed it.

I removed 4.2.2.2 and all seems copacetic. In case one wants to continue using Google DNS.
