Allium has restored normal data delivery across three major cloud platforms following a security incident, but customers using its blockchain data services still need to verify whether historical records covering the disruption have been fully recovered.
Data delivery returns, historical recovery continues
According to CryptoSlate, Allium’s Oct. 28 datashare update said delivery was operating normally across Snowflake, Databricks and BigQuery. However, the company said historical backfills were still under way for parts of its service. Backfills restore or repopulate records from the period affected by the incident, making them important for users conducting historical analysis or reconciling data over time.
Allium disclosed the incident on Oct. 28 after identifying unauthorized access to certain systems on Oct. 25. The company said it restricted access, contacted affected customers directly and brought in an independent cybersecurity firm.
On Snowflake and Databricks, Allium said raw and enriched tables for 18 blockchain networks had passed its existing checks for completeness and freshness. The networks include Ethereum, Solana, Bitcoin, Base, Arbitrum and Arc. These checks are intended to assess whether the available datasets are complete and up to date, although Allium said further validation was continuing.
Hyperliquid remained under review. Historical backfills for other networks were also continuing, as were backfills for all networks on BigQuery. That means a network that has passed checks on Snowflake or Databricks may still have a separate recovery status on BigQuery.
What users should verify
Allium said some tables may display stale “verified_until” timestamps. The company attributed the lag to the restoration of automated re-verification and said the timestamp issue did not itself mean data was missing. Users therefore need to distinguish between a delayed verification timestamp and an incomplete historical backfill.
For organizations using Allium data in research, reconciliation or software infrastructure, the relevant review involves three elements: the cloud warehouse being used, the specific blockchain network and the historical period under examination. Confirmation that the affected backfills and validation work are complete will determine when historical coverage can be treated as fully restored.
The recovery instructions also require credential changes. Existing API keys are being revoked, and users are instructed to create replacements unless an Allium contact provides one. Allium also calls for a new password and recommends enabling multi-factor authentication.
The company’s Explorer and API services were marked as restored at 10:59 a.m. EDT on Oct. 28. At the same time, new uploads and access to previously uploaded data remained temporarily disabled, preventing queries that rely on uploaded tables.
