Update

To protect your data, we've taken Acuity offline while we address PHP2SHELL, a critical security vulnerability rated 9.2 out of 10 for severity. It affects popular web software, including tools Acuity relies on, and by some estimates up to 70% of websites are exposed.

We're moving as fast as we can. Part of the fix comes from the makers of that software, so as their patches are released, we deploy them, test them and confirm they've actually closed the gap. We'll bring Acuity back once that's done.

We know how much you depend on us, and we're sorry for the disruption.
