I apologize, everyone, for Slope being down for an hour. Ironically, one of the network engineers here said he was going to take it down "for a moment" in order to improve reliability and uptime. Obviously it didn't work out that way.
In any case, I've asked him to reserve such activities in the future to non-trading hours. We are going to put Slope on multiple servers in order to improve reliability. Again, sorry for the downtime.
