A method, and associated computer system and computer program product, for notifying users of events. A notification server that includes a computer receives a notification rule. The notification server generates, for the received notification rule, a unique identifier for communication. The notification server receives an indication of an IT event that occurred in a source computing device. The received notification identifies a software hug associated with the IT event. The notification rule is a condition of a severity level of the software bug exceeding a predefined threshold. The notification server determines whether the received indication satisfies the notification rule. In response to determining that the received indication satisfies the notification rule, the notification server marks the received event, using the unique identifier and broadcasting the marked event for receipt by those users who have access to said unique identifier.
