Droplets showing DNS name resolution issues?

Anyone noticed issues with DNS resolution issues with various linux applications on their droplets?

While I can get IPs from nslookup, apps like yum seem to be having resolution errors.

Example:

Could not get metalink https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=x86_64 error was 12: Timeout on https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=x86_64: (28, ‘Resolving timed out after 30545 milliseconds’) http://centos.firehosted.com/7.3.1611/extras/x86_64/repodata/repomd.xml: [Errno 12] Timeout on http://centos.firehosted.com/7.3.1611/extras/x86_64/repodata/repomd.xml: (28, ‘Resolving timed out after 30545 milliseconds’) Trying other mirror. ^Chttp://mirror.linux.duke.edu/pub/centos/7.3.1611/extras/x86_64/repodata/repomd.xml: [Errno 12] Timeout on http://mirror.linux.duke.edu/pub/centos/7.3.1611/extras/x86_64/repodata/repomd.xml: (28, ‘Resolving timed out after 30878 milliseconds’) Trying other mirror. http://ftpmirror.your.org/pub/centos/7.3.1611/extras/x86_64/repodata/repomd.xml: [Errno 12] Timeout on http://ftpmirror.your.org/pub/centos/7.3.1611/extras/x86_64/repodata/repomd.xml: (28, ‘Resolving timed out after 30545 milliseconds’) Trying other mirror. http://mirror.cs.vt.edu/pub/CentOS/7.3.1611/extras/x86_64/repodata/repomd.xml: [Errno 12] Timeout on http://mirror.cs.vt.edu/pub/CentOS/7.3.1611/extras/x86_64/repodata/repomd.xml: (28, ‘Resolving timed out after 30546 milliseconds’) Trying other mirror.

ping resolves, but seems rather slow in pulling up the ip or doing pings.

Looking at the droplet’s load time, I am not seeing hardly any load and I rebooted the droplet recently as well.

Anyone else having similar issues?

I’m also having problems with my servers in SFO1, I would change to the openDNS servers 208.67.220.220 and 208.67.222.222.

SFO1, I believe.

It looks like Google DNS is hammered or something. I pointed my droplet to Level 3’s DNS. I would list the link I got it from, but the community forum flagged it as spam.

At the moment, nameservers are 8.8.8.8 and 8.8.4.4…

Can’t find any information for setting a closer DNS at the moment. But seeing that in nslookup now, it seems to be having issues with one of them, but refers to pulling non-authoritive answer from 8.8.8.8
