Is anyone else getting the 504 Error when managing listings?

[TessaPaige Jupiter]

Since yesterday I have been getting an intermittent 504 Gateway error when I try to manage my listings. Today I was able to see the fist 10 items of the set I wanted to list but when I tried to see and edit the rest via the drop down menu (25 items) the 504 error popped up again. 

I have contacted support about this and all they told me was that a few other people were having the same issue and they are working on it. They could not give me an idea of when this might be fixed. I was directed to submit a Jira Bug report if I wanted to so I did that too.  I am curious to know if anyone else is having this issue. I list new items for sale almost daily to MP so this is a problem...sigh.
