Oops.

Despite efforts by Superintendent Ramon Cortines and LA Unified‘s Information Technology team to get MiSiS back on track — or at the very least, semi-functional — it seems that the data management system remains unreliable.

The system went down between 2 pm and 4 pm yesterday, he said in a memo to staff. It is unclear what caused the “unexpected outage,” but any data entered into the system during that window that was not saved and will need to be re-entered.

In the memo, Cortines apologized for the disruption and for “putting you through these unforeseen challenges.”

He advised employees working in MiSiS to be “extra vigilant” and regularly save their data “every 15 minutes in the event that another unforeseen incident takes place.” Further, he’s instructed them to maintain backup records for any information that is inputted into the system for the duration of the 2014-15 school year or until further notice.

In the meantime, he has reached out to Microsoft’s top executives to provide assistance with assessing problems with the MISIS, which was developed by the district using the company’s licensed software.

Employees working overtime to address the issue will be compensated.
