SLA - Conformance to Operational Metrics

• Site Availability (Quality Metric)– Sites must have 90% availability during uptime in a

given quarter (3months) This metric is calculated as follows: If a site has degraded performance during a given day (>50% of the SFTs fail) then site is considered down for that day.

• Site declared Downtime– Sites must not be in downtime for more that 10% of

the time in a given quarter (3 months) except for reasons out of sites responsibility negotiated with country GIMs.

SLA Enforcement

• SLA should be signed by sites – not a strict legal document

• Site that fail the obligations will be discussed at next PSC

• Country rep is responsible for enforcement.– If he GIM does not do that WP3 leader should do that.– suspension of site from SEEGRID infra might be decided.

• Monitoring via SEEGRID monitoring tools and helpdesk• Duration: From the signature to the end of the project.• Site can be Temporarily suspended by SEEGRID for

security reasons.
