Este sábado a las 00:00hs UTC (1 de la mañana peninsular española, o sea, en 11 horas) haremos una parada programada de 5 a 10 minutos. Desde Amazon nos avisaron que dos de nuestros servidores centrales serían reiniciados por actualización del softwaree del servidor anfitrión:

One or more of your Amazon EC2 instances have been scheduled for a reboot in order to receive some patch updates. Most reboots complete within minutes, depending on your instance configuration. The instance(s) that will be rebooted and your scheduled reboot time(s) are listed below.

Region        Instance ID    Maintenance Window
=================================================================
eu-west-1       i-12d4e564      2011-12-19 22:00:00 UTC – 2011-12-20 04:00:00 UTC       instance-reboot
eu-west-1       i-f10b2586      2011-12-19 22:00:00 UTC – 2011-12-20 04:00:00 UTC       instance-reboot

No action is required on your part. Each reboot will occur during the corresponding scheduled maintenance window listed above. Note that when a reboot is done, all of your configuration settings are retained. You also have the option to manage these reboots yourself at any time prior to the scheduled maintenance window.

Aunque lo hacen automáticamente sin necesidad de intervención manual, preferimos hacerlo manualmente para asegurarnos de minimizar el tiempo de impacto (haremos las dos simultáneamente), y verificar que quede todo funcionando correctamente luego de los reinicios.

Disculpad las molestias.
