Looking at the numbers, I wonder about multiple issues here. Why did
the jitter values rise up that much, while the delay keeps its value?

Unless I remember wrong, delay is merely how long it takes for packets to travel back and forth to the ntp server. So it has no relation to jitter or offset. It would rather be weird if delay suddenly started changing.

...and finally: Why didn't ntpd react with increasing the poll
interval?

It's already at the max poll interval in all those reports.

ntp starts out with an interval of 64s, and backs off to 1024 eventuall, over time, if things are stable. In this case things aren't stable, but it seems to never have locked on to anything. So it's just been drifting the whole time, it looks to me.
