The assertion from the district mentioned that the glitches had focused district networks, together with these wanted to run My School Online, an internet studying platform from an organization known as K12.

That contract has but to be totally executed; a spokeswoman for the district mentioned the cash had not but modified fingers.

She added that the district would resolve by the top of subsequent week whether or not the older college students would return to the platform.
