Understanding Fastmail connection and service problems
Fastmail separates webmail, mobile apps and mail-client connections. Its status page can help identify service problems, but individual delivery failures need the recipient and error context handled privately.
The checker above requests fastmail.com from eight configured locations and shows the responses and measurement times. Compare those observations with the actual Fastmail action that failed. A homepage response alone cannot verify an account, app workflow or transaction.
For separate email & messaging services, compare these individual checks: Tuta status check, mail.com status check. Compare results separately; these links do not establish a shared outage.

Fastmail status information and official help
Fastmail help and reporting
Use the official help route for Fastmail; identify the specific product and action described on this page.
Open fastmail.com
Open the website in your browser and compare it with the result above. This link opens the service, not its status page.
Where to report problems with Fastmail
Open Fastmail help / reporting. Use the contact, technical-help or account route described there. Sign-in, support entitlement and available channels can vary; a public community discussion is not a private support ticket.
Details to include in your report
Client/protocol, read/send/login step, error code and time; do not publish message bodies, recipient addresses or app passwords.
Attach the checker’s downloaded JSON if it helps show the hostname, regional responses and original timestamps. Describe what happened in your browser or app as well. A report sent to WebsiteDown.org is not automatically forwarded to Fastmail.
What to check when Fastmail is not working
These are troubleshooting comparisons, not claims that Fastmail is currently experiencing a particular incident.
Start with the action that failed
Compare webmail access with the mail client or app that fails. Preserve unsent messages before restarting the client.
Narrow down the affected service
A bounced email, account-login error and failure to connect over IMAP or SMTP are different cases. Use the official support route with a redacted diagnostic rather than repeatedly sending the message.
Read the actual checker response
A 403 Forbidden or 429 Too Many Requests means the host answered but refused or limited that request. A timeout gives no HTTP response. Keep those outcomes separate and check the available-region count before treating the result as broad evidence.
How to check if Fastmail is down
- Compare webmail and client.
- Identify sending or receiving.
- Read Fastmail Status.
- Send redacted diagnostics.
Use the comparison and support guidance above for the specific action. Keep the original check and error timestamps together; a cached result can be older than the problem you are seeing.
A useful comparison for Fastmail
Repeat the same action in a second browser or on another available connection, keeping the item and account the same. Change one thing at a time so the result is comparable. Leave required workplace or school security controls in place.
Follow the website troubleshooting guide for connection checks. Preserve any unsent work before refreshing a form or changing a session.
