DFINITY will submit a proposal to reduce the notarization delay on subnet e66qm, similar to what has happened on other subnets in the recent weeks (you can find all details in this forum thread).
Note that e66qm is currently under high load from bob.fun, so this proposal could help increase the subnet’s throughput. DFINITY has done tests with the lower notarization delays and high load, so this combination should not cause issues.
