CSI Taxation Engine Outage
Incident Report for Rev.io, LLC
We have seen stable connections with CSI since their outage was resolved. As of this time we don't have any insight into the reason for the outage that the CSI tax engine experienced from 1/27-1/30. For this reason we ask that any questions be directed to CSI until a root cause is provided. Once a root cause is provided to rev.io we may ask that you take precautionary actions if the root cause warrants such a response.

We are monitoring the results of the fix from CSI, and at this time taxes are flowing again. We highly recommend all clients who use CSI to run test transactions and validate taxes are correct via your team and/or tax compliance partner.

A fix has been implemented by CSI and they have provided the following guidance:

Incident status: Monitoring
Our Tax Rating APIs are now online using the same endpoints you currently have. We had to change the IP addresses of the systems, so it may take some time for the DNS to propagate throughout the world. If you would like the new IP address of the endpoint, please contact me at dcazel@sybellius.net. Thank you for your patience.

We are currently receiving reports that clients who use CSI as their tax engine are not producing taxes on products or bills currently. CSI appears to be having an outage upstream from our platform. We have reached out to the CSI team for guidance and assistance. At this time, clients using CSI will be unable to run bills or create taxes until CSI has resolved the issue. We'll monitor closely and hope the CSI team is able to fix it quickly. Reach out to Client Success with any questions.
