Downloading From Dl3 And Dl4 Servers Is Restricted By Our: Data Center Work

If you encounter the restriction, follow these steps:

The official reasoning (paraphrased for clarity):

While frustrating, these reasons aren’t unreasonable. The real pain came from the lack of advance notice and broken automation.

The simplest solution. Data center work often lasts between 15 minutes and 4 hours. Try again after an hour. Many restrictions are temporary.

We rely on internal infrastructure for software distribution, updates, and large asset pulls. Historically, our automation scripts and manual workflows would pull directly from dl3.[domain].net and dl4.[domain].net. These servers are fast, internal-facing, and — until recently — fully accessible.

Then, without a formal change notice (or at least without one reaching our team), downloads started failing: While frustrating, these reasons aren’t unreasonable

After escalating to the data center operations team, we got the official word: Downloading from dl3 and dl4 servers is now restricted by data center policy.

Data center engineers regularly replace failing hard drives, upgrade RAM, patch network switches, or migrate data to new SSD arrays. During this "data center work," certain server racks are taken offline or placed into a read-only or restricted state. Downloading large files requires write operations (for logs) and heavy I/O, which can be disabled during maintenance.

The dl3 and dl4 nodes have historically served as high-throughput endpoints for external data ingestion and internal file distribution. However, recent audits of data center resource utilization revealed that unregulated access to these nodes was creating bottlenecks affecting critical infrastructure. After escalating to the data center operations team,

Some hosts allow manual server selection. Look for a dropdown menu with options like:

If dl3 and dl4 are down, choose dl1, dl2, or dl5.
