Is Gmail down right now?

Yes. HostTracker lets you add any URL - including third-party services you depend on, not just your own website - as a monitored target, and notifies you automatically the moment it becomes unreachable. Before sending an alert, HostTracker re-verifies a failure from multiple locations in its 300+-location network, so you're notified about real, confirmed outages rather than a single location's momentary blip. The free plan checks two monitors every 30 minutes indefinitely at no cost; paid plans check as often as once a minute, with alerts available through SMS, email, voice call, and several messenger apps.

Almost certainly not. Mail delivery is designed around retries: when a receiving system is unavailable, the sending server queues the message and attempts redelivery over a period that typically spans hours or days rather than giving up immediately. In practice that means messages sent during an outage arrive late, often in a burst once service is restored, rather than disappearing. The exception is a hard rejection - a bounce message telling the sender the address does not exist or the mailbox is full - which is a different failure from an outage and one the sender will be told about explicitly.

Usually yes, and the shared component is the account layer rather than any of those products. Google Workspace applications authenticate against a common identity system, so a failure there locks users out of everything at the same instant even though the underlying mail, file and document services may be perfectly healthy. The tell is that the failure looks like a sign-in or permission problem across several products rather than a fault specific to one. Checking whether mail.google.com is reachable at all from outside your network separates that from a local network or DNS problem on your side.
