Year to date
Whether the annual number is still recoverable cannot be said yet: 3 month(s) of this fiscal year have no statement, so the spend so far is not all counted.
Forecast, unchanged
Method: run rate — the closing month's daily spend, carried across every day of the next month. Stored when this statement was written, and scored against the actual once 2026-10 closes.

Each movement is attributed by the organisation's ownership rules (cloudledger rule): a tag, a linked account or a name pattern. What none of them claims is unowned, and that is the finding. The costed actions are not built yet.
Monthly report
Cloud spend in September 2026 was 53 660, 11.8% above the monthly budget of 48 000.
Not every earlier month of the year is on record here, so this report gives no year-to-date figure.
NAT gateway, eu-west-1 added 3 120: cross-zone traffic since the 04 Sep deploy of svc-media. (NAT gateway: the service that lets private servers reach the internet, billed per gigabyte it carries.)
EC2 on demand, m6i.2xlarge added 1 940: reserved capacity expired at the end of August, not renewed. (reserved capacity: compute paid for in advance at a discount, for a fixed term; on demand: the undiscounted hourly price; EC2: rented virtual servers.)
RDS storage added 870: autoscaling storage on analytics-replica, no ceiling set. (RDS: managed databases.)
S3 standard took 610 off the bill: lifecycle rule moved 40 TB to infrequent access. (S3: file storage; lifecycle rule: a setting that moves old files to cheaper storage.)
Unowned spend is 7 510, 14% of the bill, spread across 61 resources carrying no team tag. It cannot be attributed to anyone, and it will appear in every report until the tags exist.
No forecast is made yet, so this report does not say where next month lands.
No costed actions are recorded for this account yet.
