Weird..
Block 817,119 was mined at 04:44:31

3 blocks in 2 minutes, how was that possible if 1MB blocks over 60 seconds is such a danger?

Oh, maybe a one in a year event, let's go just 30 blocks further over last night:
817,089   2023-11-16 23:49:47
817,088   2023-11-16 23:47:59
817,087   2023-11-16 23:47:34

Did I miss the news on the blockchain breaking down and bitcoin becoming unusable last night when those 3 blocks in under 90 seconds happened?

We constantly mine blocks under 60 seconds from each other for years by the thousands and there has been no problem whatsoever, how could one even think this would be a threat?
