Google Cloud Infrastructure Components Incident #20003

Elevated error rates across multiple Google Cloud Platform services.

Incident began at 2020-03-26 16:14 and ended at 2020-03-27 05:55 (all times are US/Pacific).

Date Time Description

ISSUE SUMMARY

On Thursday 26 March, 2020 at 16:14 US/Pacific, Cloud IAM experienced elevated error rates which caused disruption across many services for a duration of 3.5 hours, and stale data (resulting in continued disruption in administrative operations for a subset of services) for a duration of 14 hours. Google's commitment to user privacy and data security means that IAM is a common dependency across many GCP services. To our Cloud customers whose business was impacted during this disruption, we sincerely apologize – this is not the level of quality and reliability we strive to offer you, and we are taking immediate steps to improve the platform’s performance and availability. We have conducted an internal investigation and are taking steps to improve the resiliency of our service.

ROOT CAUSE

Many Cloud services depend on a distributed Access Control List (ACL) in Identity and Access Management (IAM) for validating permissions, activating new APIs, or creating new cloud resources. These permissions are stored in a distributed database and are heavily cached. Two processes keep the database up-to-date; one real-time, and one batch. However, if the real-time pipeline falls too far behind, stale data is served which may cause impact operations in downstream services.

The trigger of the incident was a bulk update of group memberships that expanded to an unexpectedly high number of modified permissions, which generated a large backlog of queued mutations to be applied in real-time. The processing of the backlog was degraded by a latent issue with the cache servers, which led to them running out of memory; this in turn resulted in requests to IAM timing out. The problem was temporarily exacerbated in various regions by emergency rollouts performed to mitigate the high memory usage.

REMEDIATION AND PREVENTION

Once the scope of the issue became clear at 2020-03-26 16:35 US/Pacific, Google engineers quickly began looking for viable mitigations. At 17:06, an offline job to build an updated cache was manually started. Additionally, at 17:34, cache servers were restarted with additional memory, along with a configuration change to allow temporarily serving stale data (a snapshot from before the problematic bulk update) while investigation continued; this mitigated the first impact window. A second window of impact began in other regions at 18:49. At 19:13, similar efforts to mitigate with additional memory began, which mitigated the second impact window by 19:42. Additional efforts to fix the stale data continued, and finally the latest offline backfill of IAM data was loaded into the cache servers. The remaining time was spent progressing through the backlog of changes, and live data was slowly re-enabled region-by-region to successfully mitigate the staleness globally at 2020-03-27 05:55.

Google is committed to quickly and continually improving our technology and operations to both prevent service disruptions, and to mitigate them quickly when they occur. In addition to ensuring that the cache servers can handle bulk updates of the kind which triggered this incident, efforts are underway to optimize the memory usage and protections on the cache servers, and allow emergency configuration changes without requiring restarts. To allow us to mitigate data staleness issues more quickly in future, we will also be sharding out the database batch processing to allow for parallelization and more frequent runs. We understand how important regional reliability is for our users and apologize for this incident.

DETAILED DESCRIPTION OF IMPACT

On Thursday 26 March, 2020 from 16:14 to Friday 27 March 2020, 06:20 US/Pacific, Cloud IAM experienced out of date (stale) data, which had varying degrees of impact as described in detail below. Additionally, multiple services experienced bursts of Cloud IAM errors. These spikes were clustered around 16:35 to 17:45, 18:45 to 19:00, and 19:20 to 19:40, however the precise timing for each Cloud region differed. Error rates reached up to 100% in the later two periods as mitigations propagated globally. As a result, many Cloud services experienced concurrent outages in multiple regions, and most regions experienced some impact. Even though error rates recovered after mitigations, Cloud IAM members from Google Groups [1] remained stale until the full incident had been resolved. The staleness varied in severity throughout the incident as new batch processes completed, with an approximate four hour delay at 16:14, up to a 9 hour delay at 21:13. Users directly granted IAM roles were not impacted by stale permissions.

ISSUE SUMMARY

On Thursday 26 March, 2020 at 16:14 US/Pacific, Cloud IAM experienced elevated error rates which caused disruption across many services for a duration of 3.5 hours, and stale data (resulting in continued disruption in administrative operations for a subset of services) for a duration of 14 hours.

Many Cloud services depend on a distributed Access Control List (ACL) in Identity and Access Management (IAM) for validating permissions, activating new APIs, or creating new cloud resources. These permissions are stored in a distributed database and are heavily cached. Two processes keep the database up-to-date; one real-time, and one batch.

DETAILED DESCRIPTION OF IMPACT

On Thursday 26 March, 2020 from 16:14 to Friday 27 March 2020, 06:20 US/Pacific, Cloud IAM experienced out of date (stale) data, which had varying degrees of impact as described in detail below. Additionally, multiple services experienced bursts of Cloud IAM errors. These spikes were clustered around 16:35 to 17:45, 18:45 to 19:00, and 19:20 to 19:40, however the precise timing for each Cloud region differed. Error rates reached up to 100% in the later two periods as mitigations propagated globally. As a result, many Cloud services experienced concurrent outages in multiple regions, and most regions experienced some impact. Even though error rates recovered after mitigations, Cloud IAM members from Google Groups [1] remained stale until the full incident had been resolved. The staleness varied in severity throughout the incident as new batch processes completed, with an approximate four hour delay at 16:14, up to a 9 hour delay at 21:13.
