### Small Errors Automatically Handled { #small-errors-automatically-handled }

When building web APIs with FastAPI, if there's an error in our code, FastAPI will normally contain it to the single request that triggered the error. 🛡

The client will get a **500 Internal Server Error** for that request, but the application will continue working for the next requests instead of just crashing completely.

#### DNS SRV Records

Many Active Directory and other LDAP services are setup with [DNS SRV Records](https://ldap.com/dns-srv-records-for-ldap/) for high-availability of the directory service. To use this to find LDAP servers to connect to, an LDAP client makes a DNS SRV record request to the DNS service on a domain that looks like `_service._proto.example.com`. For LDAP the `proto` value is always `tcp`, and `service` is usually `ldap` or `ldaps`.
