A practical look at A records for a small hotel

21 Mar 2024

How a small hotel deals with A records — and what usually goes wrong.

The problem: query-string copies of the same page. This is where A records breaks for a small hotel.

When a small hotel asked for a quote on A records, we sent a one-paragraph email instead of a slide deck. They signed the same day.

Search consoles like honest sitemaps. Every loc should be a document. Reserving ten thousand empty shells and hoping Google does not notice is not a strategy for A records.

Most providers let you export A records as a zone file. We keep one in version control for every client. If the hosting vanishes, the zone file rebuilds the domain in minutes.

Crawlers and people want the same thing from A records: one URL, a title that matches the heading, and a next link that goes somewhere real.

After fixing A records, we added a monitoring alert. If the record changes or the certificate approaches expiry, both we and a small hotel get an email. No surprises.

When we reviewed A records, the DNS panel showed query-string copies of the same page. Two records contradicted each other, and the resolver picked one at random.
