We will be performing scheduled updates to Redis backing services on Monday the 7th of October 2024 between 9AM and 11AM.
We have sent emails to any organisation managers who manage a Redis backing service instance which we are going to update.
If you are using any of our “highly available” Redis plans, your users should only experience a small amount of downtime when the upgrade happens: up to a minute.
If you are using any “tiny” Redis plans that are not “highly available”, your users may experience up to 30 minutes of downtime.z
If you want to minimise this downtime, we recommend that you upgrade these tiny instances to “highly available” plans, ahead of the update on Monday the 7th of October 2024. You should also ensure your application correctly handles failovers ahead of time by following https://docs.cloud.service.gov.uk/deploying_services/redis/#force-a-failover to ensure that the downtime is minimised.
Note that upgrading from a tiny to a highly available plan will double your monthly charge for each Redis instance: from roughly £25 to £50 per month.
This scheduled maintenance affects: Ireland (Elasticsearch Backing Service - availability of platform-provided services via Aiven) and London (Elasticsearch Backing Service - availability of platform-provided services via Aiven).
