In a statement released on Friday August 25, Safaricom stated that the M-PESA system would be going through a planned upgrade.

“We expect all services to be restored and M-PESA to be fully functional following the process,” read the statement.

This is not the first time that M-PESA has disrupted operations as just last month they disrupted operations for similar reasons.

Safaricom had previously initiated a three-week system upgrade on June 30 which saw M-Pesa services disrupted ocassionally.
