The Keller school district’s email service was partially restored by Friday afternoon, but full email, most applications and websites were still down, school officials said Friday.
The district has not had regular Internet access since Tuesday afternoon because of a hardware failure in a main server.
All internal and external email, websites and applications went down, including online lunch payments and the Home Access Center, which tracks grades and attendance.
Technicians got email servers back up and users should begin to see new email messages in their inboxes, but sending email and accessing messages sent during the outage will take longer, said Bryce Nieman, district spokesman.
The teacher grade books, student records, payment processing and district websites should all be back online by Monday morning, he said.
Nieman said that some teachers expressed concern that previous grades they entered would be lost, but that is untrue. All grades entered as of late Nov. 10 — the day before the outage — were routinely backed up.
No data were lost, and the experience has helped reinforce the need for the district’s data recovery service, said Joe Griffin, chief technology officer.
Officials don’t think the server failed because of a virus or hacking but are not ruling out the possibility, he said.
