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

Looks like there's a DNS outage in AWS Dublin

All DNS request coming from `eu-west-1b` fail completely if you're using the default AWS DNS resolution itself - if you switch to `8.8.8.8` it's all totally fine, but that's of no use if you have private services that need internal AWS resolution

`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?

    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 / subnet / ip restrictions are setup internally.

    It'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.
