HU have just advised as below:
Dear admins & moderators,
We use a very well known tool to send our daily digests. Unfortunately, it has been having serious issues throughout the day.
What does this mean in practice?
Even after trying our best to send them, only 14% of our digests went out today. Until now, we don't have any approximate estimate of how much it could take them to solve the situation.
So, heads-up, tomorrow morning your digests might not arrive. In that case, we will post a reply here with any information we might have.
Hopefully all will be well, but if it isn't will try to let you know on this thread.
