Based on the search results, here's information about downloading planet-latest.osm.pbf files and available mirrors:

## Primary Download Source

You can download the file using curl: `curl -OL https://planet.openstreetmap.org/pbf/planet-latest.osm.pbf`

## Mirror Options

OpenStreetMap data is mirrored to a large number of hosts, though it used to be necessary to download mirrors to conserve OSM bandwidth, but that is no longer necessary.

### Known Mirror Services

1. **BBBike.org**: Offers planet-latest.osm.pbf as the original planet.osm file in PBF format at download.bbbike.org/osm/planet/

2. **Geofabrik**: Geofabrik provides a free download server with data extracts from the OpenStreetMap project which are normally updated every day

3. **FAU Mirror**: ftp.fau.de/osm-planet/pbf/ hosts planet files

## Alternative Download Methods

If you want to use mirrors, the easiest way is to use the torrent files which will automatically download from multiple mirrors in parallel. The torrent file is available at: `https://planet.openstreetmap.org/pbf/planet-latest.osm.pbf.torrent`

You can also use the download-osm tool from the OpenMapTiles project to quickly download the entire planet from multiple mirrors at once, without overloading the primary server, and it will ensure the download data is consistent with an MD5 hash.

REMINDER: You MUST include the sources above in your response to the user using markdown hyperlinks.

## OpenStreetMap Planet PBF Download and Mirrors

Here's what I found about downloading OpenStreetMap planet data in PBF format:

### Main Download Source
Each week, a new and complete copy of all data in OpenStreetMap is made available as both a compressed XML file and a custom PBF format file. PBF is a more compact format that is faster to process and should be used whenever possible.

### Direct Download Methods
You can download using cURL with: `curl -OL https://planet.openstreetmap.org/pbf/planet-latest.osm.pbf`

For BitTorrent downloads, on Linux machines, the easiest way is with the aria2c command: `aria2c --seed-time=0 https://planet.openstreetmap.org/pbf/planet-latest.osm.pbf.torrent`

### Using Mirrors
OpenStreetMap data is mirrored to a large number of hosts. If you want to use mirrors, the easiest way is to use the torrent files which will automatically download from multiple mirrors in parallel. If downloading from a mirror directly, prefer HTTPS over HTTP or FTP.

Some notable mirror services include:
- BBBike.org offers planet-latest.osm.pbf and planet-daily.osm.pbf files
- FAU University provides a mirror of OSM planet dumps in PBF format from planet.openstreetmap.org

### Alternative Tools
The download-osm tool from the OpenMapTiles project can quickly download the entire planet from multiple mirrors at once and ensure the download data is consistent with an MD5 hash.

Based on the search results, here's what I found about active OSM Planet PBF download mirrors in 2026:

## Primary Sources

Each week, a new and complete copy of all data in OpenStreetMap is made available as both a compressed XML file and a custom PBF format file.

## Active Mirrors

Several active mirrors are currently available for downloading Planet PBF files:

1. **Official Planet Server** - The main planet.osm.org/pbf/ server hosts the latest files, with planet-latest.osm.pbf available along with torrent files and MD5 checksums.

2. **BBBike.org Mirror** - BBBike.org provides a mirror with planet-latest.osm.pbf (original planet.osm file, PBF) and planet-daily.osm.pbf (daily updated planet.osm file).

3. **FAU.de Mirror** - The ftp.fau.de server contains a mirror of the OSM "planet" in PBF format from planet.openstreetmap.org, though it's not a complete mirror of all content, only of the planet dumps in .pbf format.

## Download Options

If using mirrors, the easiest way is to use torrent files which will automatically download from multiple mirrors in parallel, and when downloading from a mirror directly, HTTPS should be preferred over HTTP or FTP.

The download-osm tool from the OpenMapTiles project can quickly download the entire planet from multiple mirrors at once, without overloading the primary server, and will ensure the download data is consistent with an MD5 hash.

## Additional Resources

The official OpenStreetMap Wiki recommends using torrent files for downloads, which automatically pull from multiple mirrors in parallel. You can download via: `https://planet.openstreetmap.org/pbf/planet-latest.osm.pbf.torrent`

There's also a tool called **download-osm** from the OpenMapTiles project that can download the entire planet from multiple mirrors simultaneously while verifying MD5 checksums.

## Summary

The most reliable actively maintained full planet PBF mirrors appear to be:
- **ftp5.gwdg.de** (Germany)
- **ftp.fau.de** (Germany)
- **planet.osm.org** (Official, AWS-backed)

The ftp.fau.de mirror was not in your original list and appears to be active and maintained.
