Last week, it became evident that the Cedar GP cluster had been
 
comprimised for several weeks.  The passwords of at least two
 
Compute Canada users were known to the attackers. One of these was
 
used to escalate privileges on Cedar, as explained on
 
https://status.computecanada.ca/view_incident?incident=423.
 
 
 
These accounts were used to login to Niagara as well, but Niagara
 
did not have the same security loophole as Cedar (which has been
 
fixed), and no further escalation was observed on Niagara.
 
 
 
Reassuring as that may sound, it is not known how the passwords of
 
the two user accounts were obtained. Given this uncertainty, the
 
SciNet team *strongly* recommends that you change your password on
 
https://ccdb.computecanada.ca/security/change_password, and remove
 
any SSH keys and regenerate new ones (see
 
https://docs.scinet.utoronto.ca/index.php/SSH_keys).

Announcing a Maintenance Shutdown on December 7th, 2020
There will be a one-day maintenance shutdown on December 7th 2020, starting at 7 am EST. There will be no access to Niagara, Mist, HPSS or teach, nor to their file systems during this time. We expect to be able to bring the systems back online in the evening of the same day.

November 6, 2020, 8:00 PM: Systems are coming back online.

November 6, 2020, 9:49 AM: Repairs on the cooling system are underway. No ETA, but the systems will likely be back some time today.

November 6, 2020, 4:27 AM: Cooling system failure, datacentre is shut down.
