Question 2

Has Customer.io had outages in 2026?

Accepted Answer

Yes — Customer.io has had 13 incidents reported on its official status page so far in 2026. The full timeline (start times, durations, components affected) is shown above on this page. Pingoru re-checks the status page every 5 minutes so the count stays current.

Question 3

When was the last Customer.io outage?

Accepted Answer

The most recent Customer.io incident was "Some US customers may experience delays in message sending", which started on September 19, 2026 and was resolved on September 19, 2026. Pingoru captured this directly from https://status.customerio.com. See the full incident card above for affected components and the update timeline.

Question 4

How often does Customer.io have outages?

Accepted Answer

Based on the last 90 days, Customer.io averages 4.3 reported incidents per month on its official status page. Pingoru tracks each one with start time, duration, severity, and affected components — so you can see the pattern at a glance instead of digging through the vendor's archive.

Question 5

Where is Customer.io's status page?

Accepted Answer

Customer.io's official status page is https://status.customerio.com. Pingoru polls it every 5 minutes and renders the same data here, alongside every other cloud or SaaS provider you depend on — so you can spot multi-vendor incidents (e.g. AWS + Stripe + Cloudflare degrading at the same minute) without flipping between tabs.

Question 6

Is Customer.io down right now?

Accepted Answer

Customer.io is up. Pingoru checks the official status page every 5 minutes and flips this headline the moment Customer.io reports a change. Current status is based on 8 tracked services.

Question 7

How does Pingoru know if Customer.io is down?

Accepted Answer

We read https://status.customerio.com directly, using Customer.io's own status page. If the vendor reports an incident, you see it within one check cycle — not after someone manually marks the page as down.

Question 8

Where can I get notified when Customer.io has an outage?

Accepted Answer

Create a free Pingoru account and add Customer.io as a monitor. You can filter to specific services, pick severity thresholds, and route alerts via email, Slack, Discord, or a webhook.

Question 9

Customer.io's status page says the service is up, but I'm having issues — what's wrong?

Accepted Answer

Three common reasons:

• A real Customer.io incident that hasn't been acknowledged on their public status page yet — vendor status pages are updated manually and typically lag the first customer reports by 10–30 minutes.
• A regional or account-scoped issue affecting a subset of customers — these rarely trigger a global status-page change.
• A local problem: ISP / DNS / your own software. Try reproducing from a mobile data connection and from a different network to isolate.

If you suspect a real Customer.io issue that isn't reflected yet, contact their support to escalate. Subscribing here means you get the alert the moment they do post an update.

Question 10

Where does Pingoru get the official Customer.io status?

Accepted Answer

We use Customer.io's own status page at https://status.customerio.com. Nothing is read in a way the vendor hasn't explicitly made public — we use the same data their own dashboard uses. So our data is as accurate as what you'd see loading the status page yourself, but rolled into one dashboard alongside every other service you depend on.

Question 11

What does "Up" mean?

Accepted Answer

All tracked Customer.io components are reporting operational. No incidents are currently affecting service.
