SLA changes

GPT-5.5 Scale Tier latency SLA listed as '99% > 100 tokens per second' in the 2026-06-11 snapshot; the live page on 2026-09-23 lists '99% > 50 tokens per second'. Exact change date unknown (between those dates).

Priority Tier moved from a purchasable offer ('Get started with Priority Tier ... Higher availability: Target 99.5% uptime', still present in the 2025-11-11 snapshot) to 'no longer available for purchase' for new commitments. The 99.5% target is unchanged. Exact change date unknown; after 2025-11-11, observed 2026-09-23.

Priority processing renamed Fast mode ('Priority processing was renamed Fast mode on July 30, 2026'); service_tier 'priority' still accepted.

Credit schedule changed. The June 2021 version (Wayback snapshot 2022-02-03, PDF) gave 10% of fees when quarterly Uptime was <= 99.9% but > 99.0%, and 25% below 99.0%. The current 'Version: June 2026' page gives 5% for 99.5-99.9%, 10% for 99.0-99.5%, 25% below 99.0%, so small misses now earn half the prior credit. The 99.9% quarterly commitment is unchanged. A 2025-12-31 snapshot still linked the 20210630 PDF, so the change landed in the first half of 2026; exact day not published (date set to the version month).

Appendix A added a Snowflake Postgres HA Feature Level of 99.95% with 3x/7x/total HA-instance credits; not present in the January 9, 2026 version.

Support offerings table updated: the Enhanced tier was dropped from the current table (Business / Production / Mission Critical remain); Enhanced details retained on a separate page for existing commit customers. Page: 'Last update to offerings table February 5, 2026, for earlier version with details on Enhanced Support for existing commit customers'.

Latency SLA methodology changed from 'average request latency on per minute basis across the month' (e.g. GPT-4o 99% > 25 tokens/s in Aug 2024) to 'p50 request latency on a per 5 minute basis'. Change occurred between the 2025-04-04 and 2025-08-10 archived snapshots; uptime stayed 99.9%.

WarpStream BYOC schedule changed between the March 19, 2025 and July 25, 2025 SLA PDFs: March had 3 columns (Fundamentals/Pro/Enterprise, top band '< 99.99% ≥ 99.95%' for Enterprise, bands like '< 99.94% ≥ 99.90%'); July adds 'Enterprise Cluster (Multi Region)' at 99.999% ('< 99.999% ≥ 99.99% ... 10%') and re-cuts bands to '< 99.95% ≥ 99.90%'. The Kafka, Flink, Connector, ksqlDB and Schema Registry tables are identical in both.

20% cap on total credits (trailing 12 months of fees) and per-product scope/exclusions added. Not present in the 2025-06-15 snapshot, present on 2025-06-22. The 99.9% commitment and 10/15/20/30% schedule are unchanged since the earliest snapshot (2022-12-13).

Base support tier renamed from 'Premier Support' to 'Snowflake Support'; response times unchanged (Sev1 1 hour / Priority 15 minutes).

Support Policy: the top tier was renamed from 'Enterprise' to 'Premium'. The policy says 'No other changes were made' (support tier naming only, not uptime).

June 6, 2022 version (snapshot 2024-06-14) excluded Scheduled Downtime and printed the first credit band as '99% to 99.98%'; the July 18, 2024 version drops the Scheduled Downtime exclusion, scopes the SLA to content-serving components only (not API/CLI) and prints the first band as '99.1% to 99.98%'.

Support table changed. The Dec 2022 snapshot had Standard / Priority / Priority Plus with Urgent at '1 business hour' for all three. By the June 2024 snapshot it was Team / Enterprise Standard / Priority Plus, with Team Urgent at 24 hours. Exact change date is between snapshots.

Single Instance SLO raised from 99.5% to 99.9% (99.95% for memory-optimized family).

Enterprise availability commitment lowered from 100% (version 'Last update: April 21st, 2020', still live in the 2021-08-14 snapshot) to 99.99% ('Last updated: June 6, 2022'); the 2022 version also added a credit table (99% to 99.98% = 10%, 95% to 99% = 25%, below 95% = 50%). The 2020 text references credits 'as set forth below' but no table appears in the snapshot.

Single 99.9% Service Level (1% error threshold) replaced by dual definition adding 99.99% at a 10% Error Rate Threshold. Dec 10, 2021 version: 'The Monthly Availability Percentage for the Snowflake Service is ninety-nine and nine-tenths percent (99.9%)'; June 1, 2022 version: 'Monthly Availability Percentage of 99.99% when measured with a 10% Error Rate Threshold'. Credit multiples (1x/3x/7x) unchanged.

Amazon Compute SLA narrowed to EC2 only; the May 5, 2022 version listed EC2, EBS, ECS and Fargate as Included Services under one SLA. Percentages unchanged (99.99% region, 99.5% instance).

Instance-Level SLA of 99.5% monthly with 10/30/100% credits introduced, replacing the July 22, 2020 'Hourly Commitment' (Single EC2 Instance Hourly Uptime Percentage of at least 90% per clock hour, otherwise that instance hour is not charged).

Coverage expanded from M30+ to M10+ clusters; 99.995% and the 10/25/100% credit schedule unchanged. April 2021 snapshot (version 'Last updated: June 1, 2020') reads 'applies only to MongoDB Atlas deployments at level M30 or above'.

Single Instance SLO of 99.5% added (Jan 13, 2020 version had no single-instance commitment).

MongoDB's changelog states: 'We have updated our service credit offering for failures of uptime.' The pre-change numbers could not be verified: the earliest Wayback capture (2020-10-01) is already after this change.

S3 Standard credit schedule gained a 100% tier below 95.0% (and a 25% band 95.0-99.0%). April 4, 2018 version: 99.0-99.9% = 10%, less than 99.0% = 25%. March 20, 2019 version: 10% / 25% / 100%. Standard-IA got the same 100% tier below 95%. The 99.9% threshold did not change.

100% credit tier added below 95% for Availability Set and single-instance VMs. January 2017 edition: Availability Set < 99.95% 10%, < 99% 25% (no 100% tier); March 15, 2017 edition adds '< 95% 100%'.

Single-instance VM SLA of 99.9% (premium storage for all disks) first appears. December 2016 edition covered only VMs in an Availability Set (99.95%, credits 10% / 25%).
