How we classify services

Operational dependency warning

Relies heavily on non-European providers

Current public evidence shows 5 non-European infrastructure or email dependencies across 4 providers: Amazon SES, Cloudflare, Google, Twilio SendGrid. The reviewed operational path is therefore not entirely European.

Review dependencies ↓

UptimeRobot is an uptime monitoring service based in Slovakia. Besides checking that websites stay reachable, it monitors cron jobs, so you find out when a scheduled task fails to run, and it keeps an eye on SSL certificates.

A Slovak operator makes it a European alternative to the American monitoring services, and the mix of checks covers most of what a small operations team needs. It suits developers and site owners who want alerts for sites, jobs and certificates in one place.

Data and operations

Infrastructure and email path

Verified operational dependencies, shown separately from ownership and from the service's core data hosting.

Public website

Cloudflare

Non-European provider
Observed
A 104.26.14.202, 104.26.15.202, 172.67.71.214 · AS13335

Why this matters

Public DNS routes website visits through Cloudflare. Visitor IP addresses and request metadata can reach this non-European provider; this does not identify the core service's data location.

Incoming business email

Google Workspace

Non-European provider
Observed
MX 1 smtp.google.com

Why this matters

Published MX records route incoming business email through Google Workspace. Correspondent details and message content can therefore enter this non-European provider's systems; MX does not reveal the configured storage region.

Authorised outbound email

Google Workspace

Non-European provider
Observed
SPF _spf.google.com

Why this matters

This domain authorises Google Workspace to send email. If active, recipient details and message content can be processed by this non-European provider. SPF does not reveal its configured storage region.

Authorised outbound email

Amazon SES

US-controlled cloud
Observed
SPF amazonses.com

Why this matters

This domain authorises Amazon SES, infrastructure under US ultimate ownership, to send email. If active, recipient details and message content can be processed there. SPF does not prove active use, the selected AWS region, or use of the separately operated AWS European Sovereign Cloud.

Authorised outbound email

Twilio SendGrid

Non-European provider
Observed
SPF sendgrid.net

Why this matters

This domain authorises Twilio SendGrid to send email. If active, recipient details and message content can be processed by this non-European provider. SPF does not reveal its configured storage region.

Public DNS records identify visible providers and routes, not every backend location or private data-region setting.
