"Due to increased popularity, the segment feature is currently down so we can increase capacity. We are sorry for the inconvenience."
To that all I have to say is really? You didn't anticipate popularity with your capacity planning? LOL
And the server and app team should be able to come up with a load balanced, clustered solution that eliminates downtime for increasing capacity. You should be able to do it on the fly.
Hopefully this feature will be back up soon and with a better architecture to support future growth. :)
