How Portal-Check works

For each service we show three signals separately. This lets you see whether an outage has been confirmed by the provider, whether we measure it ourselves or whether so far only users are reporting it.

Colours

• No issues
• Maintenance
• Degraded
• Outage
• No current data
• No source available

E-mail alerts

Subscribers receive an e-mail when the provider reports an outage or our measurement detects one, and an all-clear as soon as the outage has been resolved. So that fluctuating signals do not lead to a flood of e-mails, we send at most one outage notification per service every 30 minutes. If a disruption turns into an outage, we report this immediately.

Fair requests

We query each source at most every 5 minutes, identify ourselves in the request with a contact address and respect the providers’ robots.txt. If a provider prohibits automated requests, we do not evaluate the source.

Sources per service

For developers

The current status is available as JSON: /api/v1/status, per service at /api/v1/services/{slug} and all outages at /api/v1/incidents. Please query at most once per minute.
