There was a scheduled maintenance at our hosting provider tonight that was not supposed to affect any live sites, however as we've all seen something went awry.
They broke many of their hardware load balancers, so while all our servers are up and running just fine, no traffic can get through to them for the time being.
Unfortunately, we are at their mercy, there's nothing we can do ATM except wait for them to fix the issue. (More)
Please refrain from any and all interactions with your Roos until this has been resolved. The Roo sim is shutdown until further notice because many of the vendor scripts rely on the DB being online. If you need to purchase anything you may still use the marketplace link posted above.
UPDATE: 12:15AM EST After about 45 minutes of downtime, it looks like they have resolved the issue. If you had any issues with nests during this time please file a ticket. For the next 6 hours it is possible you have some Roos show up yellow on your page until they get a chance to reconnect to the DB. You do not need to file a ticket for these, it will self correct in 6-7 hours.
