7 Possible Reasons and Their Solutions
The most common reason for site unavailability is DNS (Domain Name System) flapping, which is caused by your ISP or registrar changing your domain name’s records. The solution to fix DNS flapping is to wait until it stops. If you have to purchase a new domain name, do so before switching domains; otherwise, expect downtime of up to 24 hours while everything gets set up. Most sites are available within a few hours of DNS flapping ending.
It is common for a number of websites to be unavailable during server outages. These outages can be caused by many factors, from routine maintenance to larger problems with their network infrastructure. Some of their other customers also have problems with slowdowns.
Site Under Attack
The most serious reason for a site to go down is if it is attacked. If you think your site has been compromised, consider restoring it from backups (if available) or using another server to restore it. Be careful, as you risk further compromising the health of your site if you don’t know what you’re doing. Koddos secures your website with anti DDoS protections.
The Server Couldn't Connect to the Database
If your web server can’t connect to your database server, then it won’t be able to access your site’s data. The next step is to make sure there aren’t any problems with your hosting provider or ISP, so try reaching out to them.
Plugin Error Occurred
By default, Wordfence has been optimized to protect WordPress sites from attacks without any significant load impact. However, some of these protections may occasionally conflict with how your site normally functions.
Hosting Limits Exceeded
A web hosting service typically allows customers to upload files as long as they stay within a certain size limit. If you’ve exceeded that limit, your host will temporarily disallow any further file uploads until you reduce their size or number. Once you fix that issue, your host will re-enable file uploading.
An FTP Error Occurred
In order to maintain your website, you’ll need to use an FTP client that supports SSL/TLS. If you see a FTP connect error or similar error message when trying to connect to your site via FTP, then you may need to upgrade your client software.
