Error-log update;
The situation has barely improved from yesterday. The last measurement shows a total of 82 Eservice unavailable failures on the last 100 orders which where tried to be placed. Aka a total of 182 calls to place 100 orders.
The numbers of calls which got a correct API reply which included order ID (and other relevant info) was 51. Meaning that 49 orders where unknown after 182 calls for 100 orders. Some of these were found in the open order list, others were still not placed.
In other words 18% of the 100 calls worked out?
