Hello admins of EU AWS systems – DNS outage in eu-west-1

9 pointsby danielhuntover 8 years ago
https:&#x2F;&#x2F;status.aws.amazon.com<p>Looks like there&#x27;s a DNS outage in AWS Dublin<p>All DNS request coming from `eu-west-1b` fail completely if you&#x27;re using the default AWS DNS resolution itself - if you switch to `8.8.8.8` it&#x27;s all totally fine, but that&#x27;s of no use if you have private services that need internal AWS resolution<p>`1a` and `1c` are also affected, but to a much lower extent from what I can tell

Question for the more experienced in the group - is there a way of caching the DNS locally within you VPC in case something like this happens again? Or does that just cause more issues than it solves?<p>When I discovered it I tried switching my resolv.conf to 8.8.8.8 but of course none of my internal stuff worked because of how my security group &#x2F; subnet &#x2F; ip restrictions are setup internally.

It&#x27;s weird, I see actually most of my issues coming from instances located in `eu-west-1a`, whereas `eu-west-1b` and `eu-west-1c` look fine.

6:29 PM PST We have identified the root cause of the DNS resolution issues in the EU-WEST-1 Region and continue working towards resolution.
