Does a Zendesk outage affect your store?
When Zendesk goes down, your support operation stalls: agents cannot load tickets or get logged out, incoming emails queue on Zendesk's side instead of reaching the inbox, and embedded chat or messaging widgets on your store stop connecting. Your help center can go down too, removing self-service exactly when contact volume rises. Customers do not stop having problems during the outage, so a backlog builds and first-response metrics blow out for the day.
How can I track Zendesk outages?
Three ways, from slowest to fastest. Zendesk's official status page at status.zendesk.com/ is authoritative but often acknowledges incidents late. StatusBird's live Zendesk status page reflects independent checks every 2 minutes. Fastest is an alert: StatusBird sends SMS, email, or Slack notifications the moment Zendesk's status changes, so you find out before customer emails do.
Frequently asked questions
Are customer emails lost while Zendesk is down?
Usually not. Email is queued and retried by mail servers, so messages sent during an outage generally convert into tickets once Zendesk recovers, sometimes with delay. Chat and messaging conversations that never connected are the more likely permanent gap.
How do I keep supporting customers during a Zendesk outage?
Fall back to the raw mailbox behind your support address if you retain access to it, and publish a temporary contact route on your site or social profiles. Log every out-of-band interaction so you can create tickets afterward and keep your history complete.
How this data is measured
StatusBird checks Zendesk's status every 2 minutes, around the clock, independently of the vendor. The availability figure counts major and critical outages only; minor degradation is excluded so numbers are not skewed by vendors that report small blips near-continuously. Grades run from A+ to F. See the live numbers on the Zendesk reliability page and current status on the Zendesk status page, or browse all 84 service grades.
Know before your customers do
StatusBird monitors Zendesk and 83 other services online stores depend on, plus your own storefront, every 2 minutes. When something goes down you get an SMS, email, or Slack alert with plain-English context, usually before the official status page catches up.
