# Data Dumps (since 2008)

The self-serve Archive (Wizard and API) covers the **last 5 years**. For older data, Webz.io provides **bulk data dumps** - news back to **2008**, blogs and discussions back to **December 2014**.

## What they are

- **Format:** ZIP files containing JSON documents, organized by month.
- **Storage:** held in **AWS Glacier** cold storage.

## Coverage

| Data type | Dumps available from |
| --- | --- |
| News | 2008 |
| Blogs | December 2014 |
| Discussions (forums) | December 2014 |

## How they differ from self-serve Archive

| | Self-serve Archive | Data dumps |
| --- | --- | --- |
| Coverage | Last 5 years | News since 2008; blogs & discussions since December 2014 |
| Access | Query in the Wizard or API | Bulk, by request |
| Filtering | Filtered by your query | Whole months, unfiltered |
| Delivery | NDJSON ZIP, minutes to hours | ZIP of JSON from AWS Glacier |

## Data quality in older data

Older data is less complete than recent data:

- There is a **significant drop** in data collected prior to 2015.
- Some enrichment fields (entities, sentiment, social signals) only appear in data from around 2015-2016 onward.

## How to get them

Because the data lives in AWS Glacier, dumps are provided on request rather than instantly. Contact [sales@webz.io](mailto:sales@webz.io) to request historical data dumps for the period you need.

> [!NOTE]
> AWS Glacier is cold storage, so restoring a dump takes longer than a standard Archive order.
