hi dang, I propose a universal solution for similar instances like when a site was down or when another issue has been sorted out: the use of "[resolved]" appended to the title.

This will save you any future issues of having to find ways to reword a title to indicate an issue has been resolved while also allowing for a way for anyone who wants to analyse resolved problems an easy [resolved] tag to filter for.

I hope you don't mind this suggestion if it's feasible to standardise.
