Sharp decline in clicks and opens after Feb 15 update?

Hi all,

I've seen one post similar to this but wanted to hear from the community. We experienced a pretty sharp decline in clicks and opens after Marketo made a system-wide update on 2/15/23 in which they block IP addresses that belong to a company that provides an email security service that scans emails (their functionality leverages bots to click links in emails to scan for malicious content). 

Did anyone else go through this experience?
