Details
Filing hopefully only for posterity. Today I discovered that some of the balrogworkers (and later some other scriptworkers) stopped picking up tasks from the queue. After some investigations I realized that they were using SCL3 nameservers. Those are coming from DHCP from AWS (use1 DHCP options: https://console.aws.amazon.com/vpc/home?region=us-east-1#dhcpOptions:filter=dopt-ef162084). After manually editing /etc/resolv.conf I added a new DHCP option set wit the following nameaservers:
10.50.75.120
10.50.75.121
10.50.75.123
and applied it to the VPC in use1 and usw2. After rebooting a couple of scriptworkers, I verified that they worked fine.
I copied those IPs from my resolv.conf, so I'm not 100% sure they are correct or maybe we want to use different nameservers in different regions.
