Version control page getting blocked by firewalls

[MKatz-DHSC]

When viewing the book, I cannot access the https://best-practice-and-impact.github.io/qa-of-code-guidance/version_control.html page as it is blocked by the Department of Health and Social Care firewall.

I have queried with our IT services and it seems that the page has a "bad reputation" and was found to be malicious at some point by various vendors (see reports for the page on https://www.virustotal.com/). They have also shared another report with me that states the page is being flagged as previously is was thought to be part of a botnet.

Not sure how to solve this issue or what exactly on the page is causing the problem but might be worth investigating as the page owner.
