  • 123 Reg (hosting provider)
    • Customers lost files added since 123 Reg’s last valid backup from August, 2017.
  • partypoker

    • I missed this one last week — it was apparently due to the AWS outage I reported on.
  • TD Bank
  • Oculus Rift
    • A code-signing certificate expired, rendering some existing VR headsets non-functional. Oculus is issuing a $15 store credit to affected customers.
