How this service works
Change watch for is fastmail com down: runs the check, compares it with the result from your previous call for the same query (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
Output
Returns the current up/down status of fastmail.com, a boolean 'changed' flag indicating whether the status differs from the previous call, a diff of which fields changed with before and after values, and the timestamp of when the status was last seen. Previous check results are retained for 90 days per query.
Example use cases
Email outage early warning
“I rely on Fastmail for work email — can you check if fastmail.com is down and tell me if anything has changed compared to the last check?”
Automated uptime alerting workflow
“Set up a recurring check on fastmail.com and alert me whenever the up/down status changes — I want to know the moment it goes down or comes back up.”
Incident response verification
“We got a user report that Fastmail is unreachable — can you run a fresh status check and tell me if the result is different from last time, including what fields changed?”
Technical details
Endpoint
GEThttps://monitor.intel.rallylive.ca/watch/monitor/is-down/fastmail-com?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need change-detection semantics — not just a raw current status, but a structured diff showing whether fastmail.com's availability has changed since your last poll. Ideal for scheduling periodic checks to trigger alerts only on transitions (up→down or down→up), rather than re-processing the same status repeatedly.
Side effects
- No previous check stored (first call returns no diff data)
- Fastmail.com unreachable due to transient network issues unrelated to actual outage
- Stale comparison if 90-day retention window has expired
- Rate limiting or payment failure at $0.02 per check
