The last few days upvoting and posting on sh.itjust.works has often been slow and unresponsive.

I click on upvote and it takes a second or so to react. It also fails regularly (at least in the UI).

For posting comments, sometimes the submit button leads to no reaction in the UI. Clicking again results in duplicate posts at times.

This seems like a performance/scaling/load issue.

I have have used this instance for months and this sluggishness is new.
