The migration of significant computing power is causing a deflation of HACASH blocks. How can we adjust the difficulty to prevent the disruption caused by this migrating computing power?

From the early morning of March 8th to the early morning of March 16th, over an eight-day period, theoretically, 288*8=2304 blocks should have been generated. However, only 1593 blocks were actually produced, representing a 30% contraction.
And due to uneven block generation, transaction waiting times are prolonged, potentially up to 2 hours. This affects the experience of new users and is not conducive to promotion.
