Hi there,

Ok, there is this problem here that I do not understand, I hope someone could explain it to me.

My server is online for more than 10 days and some clients told me that they were unable to access to their website for a moment, what problem could it be?

Could it be my server down? (but its up for 10 days)
network failure for a moment?
or what? daemon service down? but how can it go up by itself if it was down in the first place?

I hope someone could answer me ... Thanks!

Could be one of several things (I suspect a network issue though).

Next time, ask your client to provide a traceroute to the server taken at the time they're unable to access it. This will tell you if the problem is network related and whether it's related to the immediate network where your server is (the DC) or somewhere closer to them in their home country/state/etc.

If it was a network issue, they will just get a timeout when trying to connect to the server and any service.

If your server was down, they'd get the same timeout. However, if you login and type 'uptime' (without quotes) you can see if this is the case. If it's 10 days then it's not possible that your server was down.

If it was httpd failure, your client would see an error message (Connection refused) message when viewing their site. Their email and other services (including cPAnel) would still work fine. You can view how long the httpd service has been running on the WHM Apache Status page. If it did fail, it's likely that cPanel's service checker noticed this and restarted it.

Just 'cause you server has an uptime of 10 days, doesn't mean the connection was constant for those 10 days. Check with whoever you have your server with to see if they had any network downtime. I know rackshack, if they're your host, was having latency problems couple days ago when an upstream provider was replacing a router.

You should really be monitoring your servers from outside soucres to check the true availablity of your services.. And not the uptime of your servers...

Yea, I have this uptime checker that checks my server 5 minutes interval, and they had reported there was socket timeout or so. Not sure what does that mean tho.
