1207867 - Redirect Sync 1.1 traffic to the EOLinator.

Status: VERIFIED FIXED

(Cloud Services :: Operations: Miscellaneous, task)

Description

[Bob Micheletto [:bobm]]

Beginning 10/1/2015 start redirecting Sync 1.1 traffic to the EOLinator service.  This includes all of the various Sync 1.1 properties: AP, REG, JPAKE, as well as the Sync 1.1 server nodes.  The privacy notice should be redirected to the Firefox accounts privacy notice.

A basic, high level plan:

1. Redirect the DNS for one or two Sync 1.1 nodes to the EOLinator service.
2. Observe and let some amount of time pass.
3. Evaluate outcome, and if everything is go, resume redirecting the rest of the Sync 1.1 nodes to the EOLinator.
4. Redirect the AP, REG, and JPAKE properties to the EOLinator service.
5. Redirect the privacy policy.
6. Begin hardware decomission.

FWIW, these may be better served by a separate service that just sends out 503s in the same manner as the 401inator, rather than re-using the custom EOLinator service designed for the storage nodes.  I believe the storage-node EOLinator will give a 404 on URLs it doesn't recognize, rather than a 503.

(Or we could change sync11eol server to 503 requests to unknown URLs instead of a 404)

We can do that at the Nginx layer with an appropriate location directive for the 503 error page:
            
   proxy_intercept_errors on;
   error_page 404 =503 /503.html; # Change 404s to 503s
