We have to make som fairly drastic changes to our consul infra, and I'm researching how to make sure Traefik stays up during this operation.
We know that Traefik handles "blips" in Consul quite well, as it runs on the "last known good" config it got from Consul if the Consul endpoint is unavailable.
My question is: How does Traefik deal with not being able to reach Consul for an extended period (120 minutes ish)? Will it still keep the last config it got from Consul, or does it ultimately restart itself or similar (leading to config loss)?
any pointers appreciated.
