Each region runs its own request from a different part of the world. A service can be up for one continent and down for another, which is usually the first sign of a routing or CDN problem.
What Apollo.io does
Apollo.io is a B2B sales platform that combines a contact database with outbound sequencing: reps search for prospects, enrich records with emails and phone numbers, and run email sequences from the same tool. Sales teams build their pipeline on it, so an outage stops prospecting and pauses sequences already running against live prospects.
What an outage looks like
Search and list building slow down or return errors before anything else does, matching Apollo's own history of search and queue degradation. Sequence emails send late or stall in the queue, and contact enrichment stops returning results, so records save with the email or mobile number missing. The web app at app.apollo.io can be degraded while the marketing site loads normally.
What to do about it
Check status.apollo.io, which tracks app.apollo.io separately from the marketing site and reports latency for background jobs, email sending and mobile number fulfilment. Much of what fails here is slow rather than broken, so give queued sequence steps time before resending. Do not re-run a large enrichment job mid-incident: empty results are hard to tell apart afterwards from prospects that genuinely have no data.
Is it down for everyone, or just you?

How we measure this
- We request Apollo.io's public endpoint every 6 hours from Fly.io regions across six continents — the most recent check ran from 8 of them.
- A region counts as down only when it gets no usable HTTP response. A
403or429means the origin answered and refused us, which we report as blocked, never as an outage. - A single failing region is treated as probe noise. We only change the verdict when two consecutive cycles agree.
- Response times average only the regions that actually served the page, so a timeout never inflates the number.
- Where Apollo.io publishes an official status feed we read it too. An all-clear from the vendor can soften an unconfirmed degradation; a vendor-declared outage only worsens our verdict when our own checks corroborate it.
