The average delay varies depending on the bandwidth provided and destination site. On average, your delay to the first router in our NOC should be between 530~570 ms.
Again, this depends on the bandwidth allocated and utilized. Take a look at your average utilization on your MRTG page. If you are using more than 85% of your allocated bandwidth (uplink or downlink), you will experience delays and even timeouts as your packets gets queued. If you are continually utilizing high percentage of your allocated bandwidth, a good solution is to upgrade your link capacity.
Definitely. Since your TCP requests or ICMP ping packets still have to go through the congested uplink, they will get queued and delayed on your router
There is a possibility that one of your servers is infected with a web worm like NIMDA or Code Red. Try to clean your server and install the latest security patches. Another possibility is that your proxy server is allowing internet users to send spam emails through it. Configure your proxy to allow only your local IPs to us it. Another possibility is that your mail server is relaying emails. Make sure you have mail relay option turned off. Finally, one or more of your users might be using a file sharing program. Check all users and uninstall these applications.
This is because of the TCP protocol windowing mechanism and the satellite delay. This doesn’t mean your bandwidth is not available. Try downloading multiple files at the same time or use software like download accelerator from This software opens multiple sessions to get the same file and would enhance your download speed.
This could be normal. Check if one of your users is downloading a large file or if file sharing programs are used.

- This error means that a TCP connection couldn’t be established with the server you are trying to access. Possible causes are congested links on your side or on the server side, Communication link error or destination server is down. If the problem persists when accessing different servers, contact our support department.
Trace route the IP address of the remote server from your PC, where does it stop responding? If it stop responding anywhere within our network or even on our upstream provider’s, then please call us. If it stops somewhere out these boundaries, then there is very little that we can do. A good idea might be to contact your remote peer and ask them to check their link and to contact their ISP.
No, Al-Harbi Telecom network is configured to never block any port so all applications should work. The problem could be locally, at your network. Check to see if you have configured the application correctly with the right information. If you have a firewall, make sure that it does support this type of traffic; configure the PC with a real IP address, outside the firewall and try your application.
You should dial exactly like using a regular PSTN line. Start with 00 + country code + Area code + number.
Dialing is like calling an international number. Just remember to add the dialing prefix before the number. The dialing prefix is different for all call speeds. Please contact our support department to get the ISDN video prefixes.
- Yes, Al-Harbi Telecom can host the files on both our redundant DNS servers. All you have to do is change the DNS servers in your domain registration form to our servers: ( & ( If your old ISP are the one who registered the domain for you, please contact them and provide them with the information above.
