Monitoring inter-site bandwidth for rebuilding

A processing system configured to implement a managing unit, the managing unit comprising:

• a computing core including associated memory;
• a network interface configured to couple the managing unit to a dispersed storage network (DSN) including one or more DSN memory devices employing a plurality of distributed storage (DS) units at a plurality of physical sites;
• the computing core configured to:
• determine a data loss rate associated with a particular physical site;
• compare the data loss rate to a communication bandwidth associated with the particular physical site;
• and
• transmit an alert message in response to determining that the data loss rate exceeds the communication bandwidth.

A dispersed storage network (DSN) comprising:

• a DSN memory including a plurality of memory devices located at a particular physical site;
• at least one processing core implementing an integrity processing unit configured to rebuild encoded data slices;
• at least one processing core implementing a managing unit configured to:
• determine a data loss rate associated with the particular physical site;
• compare the data loss rate to a communication bandwidth associated with the particular physical site, wherein the communication bandwidth corresponds to an amount of bandwidth available for rebuilding the encoded data slices;
• and
• transmit an alert message to in response to determining that the data loss rate exceeds the communication bandwidth.
