Abstract: Disclosed are various embodiments for resilient workflows dependent on external computing systems. In one embodiment, one or more steps in a workflow are determined to invoke a request to an external computing system. Availability information for the external computing system is determined. The external computing system is detected to be potentially unavailable before a request within a workflow is submitted via an application programming interface (API) for processing by the external computing system. An indication is provided that an integration with the external computing system is unavailable in response to detecting that the external computing system is potentially unavailable.

Abstract: A system for programmatically verifying electronic domain names is provided. For example, the system may receive a plurality of network domain names. A receipt frequency of a subset of the network domain names across a distributed system may be determined and compared with a receipt threshold. When the receipt frequency exceeds a receipt threshold, the network domain name may be matched with additional information that originates from a confirmation source. This information may be provided at a registration network document, which can help expedite a verification process for the user.
