When a website is not accessible, is my website still being indexed by search engines?
When a website is inaccessible, is my search engine still indexing me? Generally, a short-term failure will not immediately drop the indexing. The performance on the crawling side is usually a decrease in rhythm and an increase in retries, rather than clearing the existing index all at once. What really needs to be worried about is the duration: after the failure is prolonged, new pages cannot be accessed, and the recrawling of old pages becomes slower, the indexing area will gradually narrow. Therefore, the judgment standard is not whether there is an error, but how long the error persists and when an available status can be provided.
How long does unavailability affect indexing?
The crawling is distributed by site frequency: Sites with more frequent updates and a stable history are visited more frequently. A short-term unavailability is treated as a failed attempt by the engine, to be retried in the next cycle, and the content in the index remains. Continuous unavailability for several hours to a day will cause the scheduled crawling to fail progressively, new content to stop entering the index, and the page update time to lag behind. Repeated failures for an extended period will reduce the crawling frequency, and after recovery, a period of reconstruction is needed to return to the original rhythm. It is the most cost-effective approach to avoid the update peak during the maintenance window.
Which part of the chain should be checked first
Check the order from outside to inside, exclude one section at a time. First, check if the domain resolution has taken effect and if it has been redirected to an invalid address; then, check the port listening on the server, AnQiCMS listens by default on port 8001, when the process is alive but cannot be opened externally, the problem is usually between this layer and the reverse proxy.Next, check the certificate and forwarding rules of the reverse proxy, incorrect proxy configuration will return an empty response instead of a connection refusal; finally, check the program start status and database connection.Sites deployed using Baota panel or Docker have an easily overlooked point: the service in the panel or container is running, but the actual effective port mapping is not the one.
The misconception that robots have been removed
The easiest mistake to make during a failure is to treat robots as a switch to change. Robots manage the range of rules for allowing and prohibiting crawling, and their short-term unavailability is not related to it. However, there are two exceptions: one is the temporary addition of noindex class to the maintenance page, and the other is accidentally blocking the entire site from crawling during troubleshooting and forgetting to change it back after recovery. These two operations will really narrow the scope of inclusion, and it is difficult to distinguish the phenomenon from the failure itself. Record the original value before making changes, and set a clear review time after the change.
Actions to be taken after recovery
Service availability does not mean that the collection has been restored. After recovery, follow three steps. The first step is to verify that the key addresses return normally, including the homepage, major column pages, and recent article pages; the second step is to actively send the newly added and updated content of this period using the sitemap and link submission to accelerate rediscovery, do not wait for natural re-crawling; the third step is to review the backup and recovery records, if this fault has passed data recovery, confirm that the static files and content are within the scope of recovery, to avoid only recovering the library without recovering the files.
Common questions
Can the maintenance reminder be displayed on the page during the fault period?Can, but pay attention to the returned status code. Returning long-term cached redirects or site-wide blocking to crawlers will slow down the recovery of the re-crawling; short-term failures using 503 with recoverable ranges is more in line with reality.
Will the inclusion be recalculated after changing the server IP?The parsing, certificate, and reverse proxy layers should be checked in order. In the case that the address content does not change, the main risk is the misjudgment of site problems due to the delay in the effectiveness of parsing leading to crawling failures.
How long after recovery can you see new pages indexed?It depends on the historical crawling rhythm of the site. Active push can shorten the time to discovery, but it cannot replace the page's own crawlability and address stability.
Should a separate backup site be prepared for failures?A more practical approach is to make the backup and recovery drills a regular action, ensuring that the site can be restored in a clean environment when problems arise, rather than maintaining two parallel sites in the long term.
