How to Check Whether IONOS Is Down and Troubleshoot Website or Email Access
Check IONOS’s official status page first, then isolate whether the problem is your website, mailbox, email app, device, or connection.
Prerequisites
Have the affected website address or email address handy. If possible, use a second device or network to compare results. Do not share your password or one-time codes with anyone.
Check whether IONOS reports an outage
Open the IONOS Status page.
Find the component that matches the problem. The page lists separate components for services such as IONOS Login, Control Panel, Email, Webmail, Sending Emails, Receiving Emails, DNS, Domains, and Hosting. A green or “Operational” status indicates that the component is reported as operational; it does not prove that every individual account or website is working.
Check the incident history for an open incident, maintenance notice, or recent resolution. Match the incident’s affected component and time to your symptoms. A problem affecting email sending, for example, may not explain a website access failure.
If useful, subscribe to status updates from the page. It offers email incident notifications and webhook notifications; an email subscription requires an OTP. Do not use a subscription step if you do not want to provide an email address or complete verification.
If the relevant component is marked down or has a matching incident, wait for IONOS to report recovery, then test again. Avoid changing DNS, server, or mail settings just because one service is temporarily unavailable. If the page says operational, continue with the checks below: an isolated or newly developing issue may not yet appear there.
Separate an outage from a local access problem
Retry the affected address once, then try a different browser or device if available. If it works elsewhere, the issue may be specific to the original browser, device, or connection.
Switch between your usual connection and another available connection, such as mobile data. If access changes, investigate the original network or its filtering rather than assuming IONOS is down.
Test another IONOS service. For example, if a website fails but Webmail works, that points to a narrower website, domain, or hosting problem rather than a complete IONOS outage. This is a clue, not a diagnosis.
Record the time, affected service, exact error message, and whether the issue occurs on another device or network. These details help you compare your symptoms with the status page and explain the problem to support.
The same initial status-page check works from a desktop or mobile browser. The supplied information does not document different app menus or device-specific IONOS status features, so use the status page in a browser rather than relying on an unverified app path.
Troubleshoot IONOS email access
Check Webmail before changing an email app
If you can access IONOS Webmail, check whether the expected message is there. When it is present in Webmail but missing from Outlook, Apple Mail, Thunderbird, or a phone’s mail app, focus on that app’s account settings or synchronization rather than treating it as proof of an IONOS-wide outage.
If the message is not in the inbox, check other folders, including Spam, and look for a filter rule that moved or deleted it. Also check mailbox storage: when a mailbox is full, new email may not be delivered. Storage allowances depend on the product; IONOS’s help article lists 2 GB as standard for Mail Basic and 50 GB for Mail Business.[1]
For more detailed steps, use IONOS’s guide to email that is not arriving. It covers Webmail checks, spam and filters, storage, and email-program configuration. Those instructions are for Mail Basic and Mail Business; do not assume their plan-specific details apply to another email product.[1]
If you cannot sign in to Webmail, check the official status page’s Webmail and IONOS Login components separately. If they are operational but access still fails, note the error and contact IONOS through its official support site. Do not follow password-reset links in unexpected emails; reach the provider through its official site.
Troubleshoot website access
Open the affected site from a second device or network and check whether other websites load. If only one IONOS-hosted site fails, note that difference; it does not by itself establish whether the cause is hosting, the domain, DNS, or the site itself.
Check Hosting, Domains, and DNS on the status page, as well as any incident details that match the time of failure.
If IONOS reports those services operational and the site still fails, preserve the exact error and the time it occurred, then contact IONOS using its official support site. The supplied sources do not establish a reliable menu path for changing website, DNS, or server settings, so avoid making those changes based on guesswork.
Verify that access is restored
After a matching incident is marked resolved, or after a local troubleshooting change, reload the affected site or sign in to Webmail again. For email, check whether a newly expected message appears in Webmail and, separately, whether it arrives in your mail app. For a website, confirm it loads on the original device and, if possible, another connection. If the failure continues while the relevant status component is operational, give support the service affected, timestamps, error text, and checks already completed.
