OAuth Service Latency and IDT UI Unavailability in AMER PROD and OCI PROD
Resolved on August 5, 2026, affecting ONESOURCE Determination Enterprise Cloud (AWS AMER) and ONESOURCE Determination Enterprise Cloud (OCI AMER).
We experienced elevated latencies with the OAuth service in the ONESOURCE Indirect Tax Determination Enterprise Cloud, impacting the AMER PROD and OCI PROD environments between 11:33 AM CT and 12:06 PM CT on August 05, 2026. Additionally, the IndirectTax UI was intermittently inaccessible between 11:40 AM CT and 11:47 AM CT during this window.
