How we classify services

Operational dependency warning

Relies heavily on non-European providers

Current public evidence shows 4 non-European infrastructure or email dependencies across 3 providers: Cloudflare, Google, Postmark / ActiveCampaign. The reviewed operational path is therefore not entirely European.

Oh Dear is an uptime monitoring service from Belgium. Besides checking whether your site is up, it crawls the whole site looking for broken links and mixed content, publishes status pages, and can notify you through many different channels when something goes wrong.

Pricing is based purely on the number of pages checked, and every plan has the same feature set, so you are never pushed to a higher tier for a single option. Built and run in Belgium, Oh Dear is a European alternative to the American monitoring services, and it suits agencies and developers who look after a set of client sites.

Pricing

All plans share the same features and are priced by the number of pages checked, starting at 15 euro per month for 5 pages. The annual plan is slightly cheaper than paying monthly.

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 172.67.73.12, 104.26.7.235, 104.26.6.235 · 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 10 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

Postmark / ActiveCampaign

Non-European provider
Observed
SPF spf.mtasv.net

Why this matters

This domain authorises Postmark / ActiveCampaign 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

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.

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