On 2020-05-11 at 14:02 UTC our engineers identified that for some of their users, Avast Antivirus started blocking the Hotjar script.
From 11:38 UTC until 22:25 UTC, some Avast Antivirus users saw an intermittent error message alerting them that the Hotjar script was being blocked.
Avast flagged an IP used by our CDN Provider as blocked and intermittently showed a false-positive alert to its users about the Hotjar script.
We’ll conduct an internal investigation and will update this when we know more.
