Negative numbering to log web service update attempts

A method of logging deployment of an update to a cloud service with an update system comprising:

• an orchestrator service host computer hosting an update rollout service;
• a service bus connecting the orchestrator service host computer with a network on which the cloud service is provided;
• and
• a database to which the rollout service records a log of a deployment of an update, the log comprising an entry for each of a number of subsets of network components supporting the cloud service,
• the method comprising:
• deploying the update to a next subset of components supporting the cloud service;
• detecting whether there is an issue with deployment of the update in that subset;
• in response to detecting an issue, transitioning to a restart including marking a payload version as negative in each record in a log of the deployment prior to the restart;
• and
• restarting the deployment at an earlier subset of components that had previously received a different payload version of the update.

A non-transitory computer readable medium, the medium comprising programming instructions that, when executed by a processor of an orchestrator service, cause the processor to log deployment of an update to a cloud service by:

• deploying the update to a next subset of component supporting the cloud service;
• detecting whether there is an issue with deployment of the update in that subset;
• in response to detecting an issue, transitioning to a restart including marking a payload version as negative in each record in a log of the deployment prior to the restart;
• and
• restarting the deployment at an earlier subset of components that had previously received a different payload version of the update.
