## Considerations

* Outbound TCP sockets to [Cloudflare IP ranges](https://www.cloudflare.com/ips/) are temporarily blocked, but will be re-enabled shortly.
* Outbound TCP sockets to [Cloudflare IP ranges](https://www.cloudflare.com/ips/) are blocked.
* TCP sockets cannot be created in global scope and shared across requests. You should always create TCP sockets within a handler (ex: [`fetch()`](/workers/get-started/guide/#3-write-code), [`scheduled()`](/workers/runtime-apis/handlers/scheduled/), [`queue()`](/queues/configuration/javascript-apis/#consumer)) or [`alarm()`](/durable-objects/api/alarms/).
* Each open TCP socket counts towards the maximum number of [open connections](/workers/platform/limits/#simultaneous-open-connections) that can be simultaneously open.
* By default, Workers cannot create outbound TCP connections on port `25` to send email to SMTP mail servers. [Cloudflare Email Workers](/email-routing/email-workers/) provides APIs to process and forward email.
