The Link Rot Audit: 156 of Our 1,483 Sources Died in Three Months

Every one of our 200 when-to-visit guides lists its sources at the foot of the page: tourism boards, park authorities, weather archives, visa portals, the occasional guidebook publisher. In late August we ran a link checker over the full set. 1,494 citations, 1,483 unique URLs, 156 of them dead: one in ten. And every single dead link carried a last-accessed stamp of May 2026, twelve weeks earlier.

Three months. That is how long a tenth of a carefully curated citation list survives on the travel web, and the pattern of who died is more interesting than the count.

What "dead" actually means

We re-verified all 156 on September 3 and sorted them by cause of death. 87 return a 404: the page is gone, but somebody still pays for the domain. 43 fail DNS resolution entirely, on the apex domain and the www subdomain both, meaning nobody pays for the domain anymore. 11 serve broken or expired TLS certificates. 6 return server errors, 4 hang to a 20-second timeout, one Facebook page returns HTTP 400 to anyone not logged in, one redirects somewhere else entirely, and 3 had quietly come back to life since August, which gets its own section below.

The NXDOMAIN bucket is the one worth staring at. A 404 is a webmaster's decision; a lapsed domain is an institution switching itself off. Among the 43: egypt.travel, the Egyptian Tourism Authority portal (its successor lives at visitegypt.com), lesotho.travel, dominica.dm, uruguaynatural.tur.uy, and tuvalu.gov.tv, which was the government of Tuvalu on the country's own famously lucrative .tv domain.

The bureaucracies outlive the brands

Dead-link rate for every source we cite often, worst first:

Nearly half of our Rough Guides citations rotted and a quarter of our Lonely Planet ones, while the 157 pages we cite from UNESCO and the US State Department lost not a single URL. If you need a link to still resolve in five years, cite the bureaucracy, not the brand.

The publisher failures are not random scatter, either. Seventeen of the 53 Lonely Planet "best time to visit" pages we cited are hard 404s with no redirect: Brunei, Cape Verde, Ethiopia, Gambia, Kuwait, Nauru, Palau, Russia, Rwanda, Senegal, Seychelles, Tonga, Tuvalu, Uganda, Zambia, Zimbabwe, and Portugal's. It is not only the long tail; best-time-to-visit-japan, which we never cited, 404s today too. Rough Guides is starker still: all 14 of its dead links point at African destinations, eleven of them "when to go" pages for countries like Ghana, Malawi and Botswana.

Rot has a geography

The France, Italy, Spain, Japan, Germany, Thailand and Greece guides came through the audit with zero dead sources. Cape Verde lost six. Zambia and Bhutan lost four each; Rwanda, Senegal, Djibouti and Guinea-Bissau each lost three. In total 90 of our 200 guides had at least one dead citation, and the leaderboard reads like a map of West Africa, the Sahel, small islands and the Himalayas.

Some of what died is not travel writing but state infrastructure. Algeria's e-visa portal (visadz.gov.dz) no longer resolves. Neither does Papua New Guinea's (myevisa.ica.gov.pg), nor the Zambian immigration e-visa site we had on record. Madagascar's e-visa portal serves an expired certificate; Ghana's immigration e-services answered 503 on every attempt. These are sites people are required to use to enter a country legally.

The mechanism is unpleasant but simple. Publishers prune pages that don't earn traffic, registrars drop domains nobody renews, and both correlate with a destination being small or poor. The traveler bound for Bissau needs a live, checkable source far more than the one bound for Barcelona, and the web decays in exactly the opposite order. Pew measured the general rate: 38% of pages that existed in 2013 were unreachable by 2023. For commercial travel pages about obscure places, our numbers say the decade-scale figure is an underestimate.

Three came back from the dead

Sri Lanka's official visa-fee page, the St Kitts Scenic Railway and the site of the Saint-Louis jazz festival in Senegal were all confirmed dead in the August audit. All three answer 200 today.

Link rot flaps.

Which is why a link checker that runs once tells you less than it seems to. Domains lapse and get renewed, certificates expire and get re-issued, and a fair number of servers (climate-data.org, ReliefWeb) block automated checkers outright while serving humans normally. Our checker files 403, 406, 429 and Cloudflare's 499 as "unverified" rather than "broken" for exactly this reason; declaring a bot-walled site dead is how you end up deleting a perfectly good citation.

What we did about it

157 citations replaced and 2 removed outright, because nothing credible still exists on their subject. Replacement order: the same publisher at a new path, then the official tourism board or government portal, then a reputable equivalent, and every replacement was fetched and verified live before it shipped. The guides themselves already sit on a 90-day re-verification cycle; as of this month their sources get a separate automated check on the 2nd of every month, and failures land in a tracked issue instead of waiting for the next crawl report to embarrass us.

Method

1,494 source citations across 200 country guides, deduplicated to 1,483 URLs, snapshot 2026-08-25. Checker: HEAD request with GET fallback, desktop browser user-agent, 30-second timeout, 16 concurrent; soft statuses (403/406/429/499) counted as unverified, not dead. All 156 dead URLs were re-verified on 2026-09-03 with curl and dig, apex and www both, before any number in this piece was written down. Final tally: 87 × HTTP 404, 43 × NXDOMAIN, 11 × broken TLS, 6 × server errors, 4 × timeouts, 3 recovered, 1 off-domain redirect (Uzbekistan's tourism site now forwards to a generic government portal), 1 × Facebook's HTTP 400 wall. The dataset is the sources section at the foot of every when-to-visit guide; rot rates by publisher were computed against the full pre-repair citation set.
