A lot of the software on heron (the ssh and email server) is slightly out of date, and on the distribution itself we are a major version behind. Of course, it’s Linux, you just upgrade it and never reboot, right? Unfortunately, we do need to take it down briefly tonight. Downtime will start at 11pm EST and should last no longer than one hour. We apologize for the inconvenience.
Update: Heron is back up, and upgrades are underway so the system may be a little slow and will probably be restarted again tomorrow night (I will post another update if that is the case.)
Update #2: The upgrades are finished and it doesn’t look like Heron will be restarted tonight.
