Is WFH infrastructure up to the task of dealing with expanded traffic?

I don't work for a technology company. We have citrix, and on a good day it can be sluggish. I am already on WFH due to local school shutdowns, and many more are following. Citrix is already (though functional) less responsive. I doubt my situation is unique.

What are the capabilities of those of you working in non-tech organizations to ramp up resources here?

Same question for those of you working in tech companies, are you better situated to scale this aspect of your infrastructure?
