Are there clever solutions for routing traffic to other linode datacenters during one of these outages? I'm moving to AWS if I can't do something akin to elastic ip across datacenters. Linode currently only allows you to swap ip addresses within a dc.

use a DNS roundrobin with low TTLs and use monitoring to remove IPs when they go down. if you have 3 hosts in your production app's roundrobin, that makes it much less likely that they'll hit the dead server and if the TTL is 300, then it's only a few minute window anyway.

That's material for a great blog post. Please write an article wherever you can and share!
