"Thank you for your patience with us. There is a known issue with our external pool connections that our developers are still working on. They are in connection with the developers of those external pools to find a way for the connection to work as before. This will be resolved shortly. Meantime, please point your workers to Mintsy Pools for better hashrates. Once we have connection with external pools we will inform you."
Rubbish, this has nothing to do with the external pools and in any case how would they know which pools do we want to use?
I got an answer that they have a problem with assigning/matching the hardware with a pool and this sounds likely.
But still it looks like they are telling different people different stories and most of them are just that.
