Top-BDIIs considered for NGIs core services availability computation
The following table contains the list of the NGIs' Top-BDIIs. These instances will be used to calculate the monthly NGI's availability reports. Please report mistakes in the liste below to operations@egi.eu, or correct your entry.
- More NGIs may report the same Top-BDII, if they are sharing the service (e.g. if they have a common Operations Centre).
- NGIs can report more than one service, if they have set up failover at client side using multiple Top-BDIIs. The result availability will be calculate as an OR of the single Top-BDIIs availability (hourly).

Computation algorithm
A brief description of the algorithm used for the availability calculation.
There could be two different scenarios:
- The NGI reports only one Top-BDII. It could be a single top-bdii instance, or an alias for a DNS pool, but it has to be monitored by the NGI Nagios. If the alias is used by the sites but only the single instances in the pool are monitored, the NGI should enter the list of the instances. In this case the Availability and Reliability statistics are calculated asking directly the monthly values for the service to MyEGI.
- The NGI reports a list of Top-BDII that are used by the sites to configure failover at client side. In this case the steps are the following
- Query MyEGI to get the hourly A/R values for every top-BDII listed
- For every hour the best availability performance is selected from the hourly availabilities of the single top-BDIIs. The same for the reliability.
