4) Technical Issues
• Define a rule for when it is appropriate to release this info• Will need to be mindful of:
• Severity and duration• Contract• Storage Portfolio
• GGPSSO – 6.8 Where unplanned disruptions [occur] the SSO shall ensure current system users are notified .. ASAP• but no sooner than….X (?)
