Dear User, Last Sunday evening we experienced an unplanned major power outage that shutdown our building systems and closed all lab and cleanroom operations. We also had a UPS repairs scheduled for this week that will close our lab and cleanroom operations for this week and was planned several weeks ago (email below). These signs have been posted on all doors at the same time as the email. We have recovered this afternoon from the unplanned power failure from last Sunday evening. But we still need to complete the UPS repairs planned for this week as well. At this time we hope to have the UPS repairs completed and have all lab and cleanroom operational by Friday at 4PM. An email notice will be sent out if the repairs are completed earlier. Please contact me if there are any questions or concerns.
