Planned downtime @ Rackspace

Greetings,
 As some may be aware, we are currently working with Rackspace to upgrade the PostgreSQL infrastructure systems which
theygraciously host for us.  As part of these upgrades there will be downtime for systems hosted there. 
 Our first planned downtime will be for ~ 2 hours on Monday, April 28th, between 1500-2000 UTC (11am-4pm US/Eastern).
Wehave requested that the outage be towards the end of that window (1800-2000 UTC), but there is no guarantee that
they'llbe able to support that request. Clearly, we hope the actual downtime will be less than 2 hours. 
 This downtime will impact all systems hosted @ Rackspace as they are upgrading the switch for us.  End-user services
whichwill be impacted include: 
   yum.postgresql.org   wiki.postgresql.org   git master server (Committers only)   planet.postgresql.org
www.pgadmin.org,ftp.pgadmin.org   media.postgresql.org   commitfest.postgresql.org   developer.postgresql.org
(Developerpersonal homepages)   redmine.postgresql.org   jdbc.postgresql.org   postgresopen.org   developer.pgadmin.org
(sandbox,Jenkins)   babel.postgresql.org (Translation services) 
 Redundant services (minimal impact expected):   ns2.postgresql.org (other nameservers will still work)   .us inbound
mailrelay (other MXs will still work)   .us website front-end (should be removed from pool)   FTP mirror (should be
removedfrom pool) 
 We anticipate this being the only whole-environment outage during this migration.  Future outages will happen for
individualsystems as we migrate them to the new hardware.  
   Thanks!
       Stephen
