The test phase start windows are closing in short. The online phase start window will close:

Friday, 29th of May, at 12:00 GMT

And the offline (only) phase will close on:

Monday, 1st of June, at 12:00 GMT (in 4 days)

I.e., by those dates participants must have either told us which of their servers are ready, or have sent us at least one valid training run together with their team ID for the offline participation (online teams can choose to participate offline after completing their online phase).
