← Glossary / Data Residency

What is Data Residency?

Data residency refers to the physical and geographic location where scraped data is processed and stored. In web scraping, it dictates not just where your database lives, but where your proxy exit nodes, extraction workers, and delivery buckets are physically located. For enterprise pipelines handling PII or regulated public data, crossing the wrong border during extraction can trigger immediate compliance violations.

Why the physical location of your scraping infrastructure matters just as much as the data you extract.

TL;DR

Data residency laws require that certain types of data remain within specific national borders. For a scraping pipeline, this means ensuring that the proxy IP, the compute node running the headless browser, and the final storage bucket all reside within the mandated jurisdiction. A single misconfigured worker in the wrong AWS region breaks the chain.

01Definition & scope

Data residency is the legal and operational requirement that data must be stored and processed within a specific geographic boundary. In the context of web scraping, it applies to the entire lifecycle of the extracted data: the proxy exit node that receives the initial HTTP response, the worker node that parses the DOM, the message queue that buffers the records, and the final database that stores them.

02The scraping residency chain

A compliant pipeline must maintain a localized chain. If you are scraping UK public records containing personal data, your proxy must be in the UK, your extraction script must run on a UK server, and your S3 bucket must be in eu-west-2. If your proxy is in the US, the data technically leaves the UK during transit, violating residency requirements before it even reaches your database.

03Cross-border transfer risks

Regulations like GDPR and the DPDP Act place strict limits on transferring personal data to countries without adequate protection standards. Scraping pipelines are highly susceptible to accidental transfers due to auto-scaling cloud infrastructure, global proxy networks, and third-party APIs (like translation or CAPTCHA services) that process data outside the mandated region.

04How DataFlirt handles it

We build region-locked extraction environments. When a client requires strict data residency, we deploy dedicated Kubernetes clusters in the target region. We bind the proxy gateway to local ASNs, run headless browsers on local nodes, and execute ML models for anti-bot bypass entirely within the cluster. Telemetry is scrubbed of payload data before being sent to our central monitoring plane.

05Residency vs. Sovereignty

While residency dictates where the data sits, sovereignty dictates whose laws apply to it. Storing EU data in an AWS data center in Frankfurt satisfies data residency. However, because AWS is a US company subject to the CLOUD Act, some argue it does not fully satisfy data sovereignty. For highly sensitive government scraping contracts, sovereignty requires using domestic cloud providers.

DataFlirt provisions region-locked extraction clusters for sensitive pipelines. When strict residency is enabled, the proxy pool, the Kubernetes worker nodes, the Redis queues, and the delivery sinks are all physically constrained to the target jurisdiction. We disable global fallbacks and route telemetry through local aggregators to ensure no regulated byte ever leaves the zone.

Common
questions.

About data residency, cross-border scraping compliance, and how DataFlirt isolates infrastructure.

Ask us directly →

Does data residency apply to publicly scraped data? +

Yes, if the public data contains Personally Identifiable Information (PII). Under GDPR or India's DPDP Act, the public nature of the data does not exempt it from residency and cross-border transfer restrictions. If you scrape a public directory of EU professionals, processing that data on a US server is a compliance event.

Can I use a global proxy pool if my database is local? +

No. The proxy server processes the data in transit. If an EU target's response flows through a US proxy before reaching your EU database, the data has crossed borders. Strict residency requires geo-targeted proxies that match the required jurisdiction.

What is the difference between data residency and data sovereignty? +

Data residency is the physical location where data is stored and processed. Data sovereignty means the data is not only physically located in a specific country but is also subject exclusively to the laws of that country. Sovereignty often requires using local cloud providers rather than local regions of foreign providers (like AWS).

How does DataFlirt guarantee proxy locations? +

We use ASN and IP geolocation verification on our proxy pools before routing requests. For region-locked pipelines, we restrict the proxy gateway to only lease IPs physically located in the target country, dropping any request that attempts to route outside the geofence.

Do CAPTCHA solvers violate data residency? +

They can. Many third-party CAPTCHA solving services require you to send the page URL, site key, or even DOM snapshots to their APIs, which are often hosted globally. If the DOM contains PII, this is a residency violation. DataFlirt uses localized, in-cluster ML models for solving challenges on strict-residency pipelines.

How do you handle failover in a region-locked pipeline? +

We use intra-region Availability Zone (AZ) failover. If an extraction worker in eu-central-1a fails, the job is retried in eu-central-1b. We explicitly disable cross-region failover (e.g., falling back to us-east-1) to ensure the residency constraint is never breached, even during an outage.
