My site is down for me only or for everybody, how can i resolve this?
This article is lengthy, but it is very important you go through it as this is a major challenge every blogger encounter with his/her hosting company.
Few people know what to do when they cannot access their website on their system or any device while some don’t.
If you find out you can’t access your site, first thing you need to do is to confirm if your ISP IP is globally blacklisted. Check Blacklist here: www.whoer.net
If it is blacklisted, your IP will probably be blocked by your web server due to its cPHulk Brute Force Protection or ConfigServer Security & Firewall.
You can copy your IP and forward to your web server provider or hosting company to whitelist your IP. By so doing, you will have access to the site; although this might take a little while to be resolved if your hosting company did not respond on time.
Meanwhile, if you are in haste, you can use VPN to get a new IP, then try again.
Another reason why your site is inaccessible, it is rare this days for servers to go down except if the web server provider is still operating in the 19 century.
Most hosting companies that has vps or dedicated server now use Cloudlinux OS Base server which enable them host multiple sites on the server, so therefore, the server will always be up, but the tenant sites may go down if they have over used there allotted resources like Virtual CPU, Virtual Ram, Ionodes etc.
CloudLinux OS is the leading platform for multitenancy, It improves server stability, density, and security by isolating each tenant and giving them dedicated server resources.
If this is your issue, you can manually increase your site memory using php.ini
If you follow these instructions and it still doesn’t work, try renaming the file to php5.ini. Once the file is open, add or edit the following lines and then save and close.
upload_max_filesize = 1000M
post_max_size = 2000M
memory_limit = 3000M
file_uploads = On
max_execution_time = 180
The M means megabytes. Change the 1000M, 2000M and 3000M limit to the value with which you feel most comfortable. Changing the value of max_execution_time will limit the amount of time spent loading a script in seconds.
In many cases, the values you enter should get larger as you go down the list from lines one to three. The upload_max_filesize should be the smallest while memory_limit should be the largest. The median should be post_max_size.
