TRS 2 will be closed for maintenance on Monday the 31 January.
It will still be possible to submit TR files, but feedback will not be sent until the maintenance has been completed (noon the 1 February).
The reason for this postponement is that the European Securities and Markets Authority (ESMA) has posponed a deployment operation for a new release of the Financial Instruments Reference Data System (FIRDS).
This also means that TRS 2 will be in operation Monday the 24 January.
