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
