Update - We have received an update from Carlton One/GRS. Unfortunately it appears that their service may be down for an additional 24 hours. Thank you for your understanding in this matter.

We are following up on our earlier email regarding the unusual activity identified within our environment. Our investigation remains ongoing and affected production systems remain offline as a precautionary measure while that work continues.
Based on our current assessment, we expect services to remain unavailable for at least the next 24 hours. Our priority is the safety and integrity of our systems, and we will begin restoring services as soon as we determine it is safe to do so.
