What tech opportunities has your company taken advantage of since COVID-19 killed your traffic and revenue?

I'm a developer for an e-commerce site. Our traffic is severely reduced due to the nature of our business being affected by COVID-19.

We are now focussing on major tech debt to fix that would have otherwise been too risky, or needing heavy coordination to keep continuity (DB tuning and upgrades needing restarts, blocking traffic while we implement a breaking change to a data model used by all apps, …).

What has been prioritized and what have you been able to fix that's been a thorn?
