We are currently investigating an issue causing abnormal connection terminations for services in the Azure - EU West region. Impact: The issue appears to be limited to a small number of sites that use an A-record to point directly to the 20.50.222.94 and 20.54.176.184 IP address due to LB connectivity issue. Current Status: Our engineering teams are restored LB connectivity becomes available and actively keep monitoring. Immediate Recommendation: For affected customers, we recommend temporarily changing the A-record pointing from 20.50.222.94, 20.54.176.184 to **20.107.95.65, 20.107.95.95** from your DNS configuration to mitigate the impact. If possible, we also recommend using a CNAME record instead of an A-record, which provides greater flexibility in handling future changes.

The LB connectivity traffic has been restored. Action Recommendation: For customers **who switched the A-record to temporary LB IPs (20.107.95.65 and 20.107.95.95)**, these addresses will continue to be available for the next 48 hours, we kindly recommend updating your DNS A-records pointing back to **20.50.222.94 and 20.54.176.184** at your earliest convenience to ensure uninterrupted service. If possible, we also recommend using a CNAME record instead of an A-record, which provides greater flexibility.
