Is it me only that the website is slowed down recently?

It takes a few minutes to load properly and it’s still loading while I’m starting a thread here. Is it something to do with the Forecast AI beta?

Forecast AI runs local to each user so very unlikely to cause a slowdown. Always check for network issues when you’re seeing any slowdowns. We have much more than enough capacity so not likely to be a general problem. Sometimes a user may have some faulty data that can cause some calculations to fail and timeout. You should contact support to get these resolved.
