Companies Using Fedora

At Bing I learned that server banners are the cheapest signal a crawler collects and the easiest to misread. Fedora shows why. A domain counts here when its web server answers with a Server header naming Fedora, such as Apache/2.4.68 (Fedora Linux). Our October 2026 crawl finds 1,461 live domains like that, 766 of them matched to a company, 9th of 16 in Operating Systems. Before trusting the number I wanted three answers: are the banners still there, who writes them, and who sits behind them?

The banner is still there, and often old

On 15 October 2026 I requested 50 random Fedora domains again. 46 sent a Fedora banner, two of them after a redirect, and four didn't answer. 31 of the 46 used the newer "(Fedora Linux)" label and 15 the older "(Fedora)". The version numbers tell a second story. Fedora releases about every six months and supports each release for roughly 13 months, according to its release life cycle, and its two supported releases in October 2026, 43 and 44, had received Apache 2.4.68 and 2.4.69 since June. Only 17 of the 46 carried those builds. The rest went back as far as Apache 2.2.9, and 15 still named an OpenSSL 1.x library.

Sales signal: a Fedora banner with an old Apache build marks a server nobody has upgraded in a long time. Managed hosting, migration and security services get a concrete opening line from the banner itself.

Flat since July

The chart reads 1,111 in June, 1,358 in July, 1,412 in August, 1,453 in September and 1,461 in October. The June to July step is our crawl covering more of the web and our detection widening, and the domain list itself turns over each month as dead sites leave and new ones arrive. Since we began tracking Fedora in March 2026, 152 domains have dropped the banner. 31 of those still send it from another hostname, so about 121 left entirely.

"A Fedora banner is a choice somebody made on one specific machine. On a public web server that's unusual, and the version string usually tells you how long ago they made it." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: treat this as a stable pool of roughly 1,400 domains. The value is in what each server says about the people who run it.

Who writes the banner

The site owner rarely picks the operating system; whoever built the server does. I resolved all 1,451 domains in our clean set and grouped them by network. 183 sit on AS24679, a hosting network run by kyberio GmbH of Hanover, and 148 of those are German .de sites: tax advisers, roofers, care homes, a Buxtehude restaurant. Another 531 run on cloud servers at DigitalOcean (123), AWS (122), Akamai's Linode (115), OVHcloud (89), Hetzner (53) and Contabo (29), where a developer picked Fedora as the image. Single owners show up too: one server in Poland carries 20 product sites for one drug maker.

Sales signal: in the German cluster the buyer is the hosting company, not the 148 businesses on it. On the cloud servers the buyer is the developer or agency that runs the machine.

Small firms, universities and one gear maker

65.05% of matched companies with a known size have 1 to 10 employees and 21.53% have 11 to 50. Age points the same way: the 2000s (27.21%) and 2010s (25.37%) lead, and only 8.09% were founded in the 2020s. The big names are mostly one system inside a large organisation. UNAM runs Fedora on its student-guidance site, the Medical University of Sofia on an academic-careers portal, Bharathidasan University on its exam portal, and Mars Hill University and IIT Goa on Moodle. Nidec is the odd one out: www.nidec-dtc.com, the main site of its gear-reducer business, answers with Apache/2.4.69 (Fedora Linux) and mod_perl.

Sales signal: at universities the buyer is the department that owns the server, often e-learning or exams. Pitch to that team first.

The US, Germany and the Moodle servers

The United States leads with 185 matched companies, but Germany is close behind with 160, largely because of the kyberio network. France (46), the United Kingdom (30), the Netherlands (29) and Poland (26) follow. By industry, IT Services and IT Consulting leads at 6.3%, Software Development has 5.95% and Higher Education 3.5%. The top ten industries add up to only about 36%, so the base is horizontal. What ties it together is a technical person who chose the OS.

Sales signal: for developer tooling or managed Linux, the IT-services and software firms here are the closest fit. For German small-business services, start with the hosting network that serves 148 of them.

Where Fedora servers go

The switching data is small, and it describes servers. Since tracking began, 15 domains moved to AlmaLinux and 11 to Debian, while 4 came from Debian. When I looked up the addresses, 12 of the 15 AlmaLinux moves were Brazilian regional news sites sharing one server, and 7 of the 11 Debian moves were Czech sites on another. Two rebuilt machines explain most of the movement. Overlap is commoner than switching: 23 domains run Fedora and Ubuntu on different hostnames today, and 13 run Fedora and CentOS.

"Two rebuilt servers account for 19 of the 26 domains that left Fedora for a system we can name. On a header signal, a switch is usually one administrator's weekend, not a market trend." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: a Fedora server is a rebuild waiting to happen. The ones on old Apache builds are the likeliest to move, and when they do, they tend to land on AlmaLinux or Debian.

The stack around it

Apache runs on 99.79% of Fedora domains because Apache writes the label; a Fedora server behind Nginx or a CDN never appears here. OpenSSL shows on 93.25%. PHP is on 61.61% and WordPress on 33.98%, with Elementor on 11.58%. mod_perl and Perl are on 13.92% and Python on 5.79%, and Nidec's banner lists mod_perl too. Cloudflare fronts just 5.17% of these domains, which fits servers that answer the web directly.

Sales signal: these are self-managed Apache servers with PHP and WordPress on top. Hosting migration, WordPress maintenance and server hardening all fit.

Key takeaways

1. 1,461 live domains, 9th of 16 in Operating Systems, and 46 of 50 sampled servers still send the banner.

2. Only 17 of those 46 ran the Apache builds Fedora currently ships.

3. One Hanover hosting network carries 183 domains; cloud servers carry 531.

4. A small-company base, 65.05% with 10 or fewer staff, plus university systems.

5. Switching is rare and mostly whole servers: 19 of 26 named moves came from two machines.

How to use this list

Filter by country and company size, then group rows by server address, because one machine often carries many domains. For the full list of 1,461 Fedora domains with company, size and stack data, explore TechnologyChecker.io.
