Why aren't we told what the reason is of the downtime? Or did I miss it in this thread?
We are updating the site at the moment and maintenance will take longer than expected.
That's not a lot of information for such a big site.
Whatever it is, I am glad they have are doing it now during a weekend when very little action is taking place on the order books. If they can resolve some of the load issues they were experiencing during peak trading hours it will be well worth the wait in my opinion.
