Hi,

We'll be replacing the batteries in our backup power supplies on Sunday Jan 22 at approximately 1pm EST. This means that all servers (S1 to S7) will be powered down and restarted within that hour - this will affect the Carleton Bio2RDF mirror, Carleton-hosted SADI services, SIO ontology, HCLS endpoints, MASCOT, and a variety of web sites. We'll send an email when everything is back up, and please let me know if your hosted service(s) are not responding.

Thanks for your understanding,

Hi,

Unfortunately, server s6 (hosted SADI services) & S7 (SADI dev machine) did not come back up (kernel panic) after completing our battery replacement. We suspect it's related to the SSD drives that they run on. We're going to look into solutions for this today, but it's likely to take a couple of days.
