Gaps in kline data

API Spot/Margin API
#1

When I request the one-minute-klines of BTC/EUR for the past few months I see some gaps between the klines. So sometimes complete hours of data are missing:

2020-12-25 from 02:00 to 03:00.
2021-02-11 from 03:41 to 05:00.
2021-03-06 from 02:00 to 03:30.
2021-04-20 from 02:00 to 04:30.
2021-04-25 from 04:01 to 08:45.

Can someone confirm?

And if so… what happened? Did someone pull the plug? Maintenance? Some weird summer-to-winter-time-thing? Did we travel forward in time? (See my previous question).

Hi. Can you provide more info about this, such as:

  1. How did you query the data, from API or from public data download site?
  2. How did you observe the missing data? For example, given 2020-12-25 from 02:00 to 03:00 data is missing, does it mean you were able to find the record at 2020-12-25 from 01:59 and 2020-12-25 from 03:01?
