it is not nonsense. It does happen at IB every night. IB loose connection once every 24 hours (any farm, slightly past midnight of farm time). We are in US, and it was typically between 12:10-12:30am window. Markets are open at this time, and we had enough issues with entering and exiting positions (not often but often enough), to make us switch to another broker.
However, the issue of this thread, has nothing to do with it.
IB has a 'strange' backup system.
every day, it will disconnect for about 5 minutes.
If you are connected to the IB US server,
the backup will be done during your evening/night time.
If the connection is to the IB Asian server,
the backup will be done during the later part of the European session.
as you said, the issue of this thread is a different problem.
