Starting yesterday afternoon, /global/b has returned to service on all Sharcnet clusters. We apologize for the extended outage, and believe that there was no loss of data. In recognition of how this outage was disruptive to 1/3 of users, affected users will be given higher inter-cluster fairshare/priority.

If you notice problems, please report via the ticket system: help@sharcnet.ca or https://www.sharcnet.ca/my/problems/submit
