I've experienced quasi-remission twice now. Both times when I got so sick from food in a foreign country that I couldn't eat for days (and had no appetite for it either). I lived on water. Afterwards, for 1-2 weeks, I did not require insulin (while eating a lot).

I used to think it was due to the pills they gave me there, or perhaps due to the bacteria (or virus?) causing some strange temporal abating of auto-immune response and regrowth of beta-cells. But seeing this is making me reconsider that (I was doubting the effect of the medicine since I took some home and took it in a healthy state but did not get the good effects).

I've been Type 1 for 20+ years and have measurable remissions based on blood tests. Low level functioning of pancreas again.

The thing that moved the needle for me was fasting + ultra running (which from my understanding implements a fasting-like response by the body in some ways).

Interesting that not eating for a while correlated with what seems like increased pancreatic activity...

How long did you fast for? Or did you do intermittent fasting?

A little of both. Intermittent fasting didn't seem to have an impact. Longer fasts (longest I've done is 3 days) definitely do, I seem to have better control for the days following it.

But that doesn't look like remission, you still need insulin...? Better control after long fast is expected (using insulin). Have you done c-peptide or antibody tests?
