Performance Statistics: Paris - Washington

Availability Including Planned Outages: A Planned Outage is a temporary and unavoidable interruption in service that is necessary for Apollo to carry out essential maintenance work or network upgrades. These statistics show Apollo’s performance each month including any planned outages.

Availability Excluding Planned Outages: These statistics show Apollo’s performance for each month excluding any planned outages.

12 month Average Excluding Planned Outages: This calculates the 12 month average for availability exclusive of any planned outages.

Target Including Marine: The theoretical target availability for the Apollo Network, including backhauls, is 97%. However as Apollo is an unprotected system, these cannot be guaranteed. The calculation is based upon the following assumptions:

• On the submarine system, the mean time between failures is once every two years, with a mean time to repair of 14 days.
• On the backhauls, the mean time between failures is twice per year, with a mean time to repair of less than 24 hours.
