firewall allowlists

The firewall allowlists tag on WindowsForum.com covers practical discussion of maintaining explicit allowlists for network access, with a focus on how infrastructure changes can break tightly scoped firewall and proxy rules. Recent content examines GitHub Actions adding new blob-storage hostnames to its Meta API, noting that organizations permitting Actions storage host by host must update their firewall and proxy allowlists or risk losing access to job summaries and logs. The discussion frames this as an infrastructure change rather than a new feature, and highlights the operational discipline required when allowlists are maintained at the hostname level instead of broader ranges.
