Grid operators have many ways to measure the severity of an outage. In Europe, this is commonly done using the Incident Classification Scale [0]. The term "giant" is not any official terminology, but that particular outage would be considered an "Extensive Incident" (red) due to it being in the T2 category, ON2 category, and possibly in the L2 category (maybe L1, I don't know the Latvian grid well enough). A lot of people in the industry would say that a 'red' incident is 'giant', as they tend to have high standards for reliability and security.
