These FAQs section is intended to provide answers to basic questions about the RETN NOC, Customer Portal and some major service issues. For more information about our network and services check out the links below the page or send a request using the contact form.
Any time you experience a problem with our service or have a technical question about the service provided by RETN. Our technical team is available 24x7x365 and support all clients of RETN Group of Companies who buy our services.
All you need to get the support is tell us your Customer ID and Service ID and explain the issue clearly when contacting the RETN NOC.
The most preferable way to contact the RETN NOC is by e-mail to email@example.com or via online contact form. Your request won’t be left unattended as all engineers at RETN technical department receive these emails. For urgent matters you can use one of direct phones. See all options to contact NOC here.
This is a supporting platform that allows you to:
– check the status of your invoices
– access the list of contacts responsible to solve different kinds of issues
– check the list of services you are and service status
– examine traffic charts, such as traffic load rate, inbound and outbound traffic amounts
– open trouble tickets and trace them
This statistics is available only upon request. Please, consult your account manager.
You should contact the RETN NOC, indicate your Customer and Service ID and describe your problem. If the issue is connected with particular resources, the message should contain traceroute output with fixed source and destination (IP address). If possible, please also provide us with the reverse traceroute.
Yes, we have a Blackhole community 9002:666, for more information see BGP Communities section. A blackhole announced by a client gets validated (i.e., it is verified whether the best path to the announced more specific route is chosen via this IP-transit BGP session) and is spread throughout the RETN’s network. The maximum amount of blackhole routes which can be received from one BGP-neighbour cannot exceed 100 routes.
At the moment the new blackholing system is fully operational. The old system (multihop-session with a blackhole server) is taken out of service.
If you are already under DDoS attack and urgently need to set up a filter on RETN’s network side, you should contact our NOC team by email and by phone to ensure immediate reaction. If you wish to get a better protection and avoid new DDoS attacks in future, get to know more about protection methods we offer here.
If you wish to have a specific filter (filtering by interface, bandwidth limitation etc.) configured by RETN permanently for your service, you should contact your account manager. Permanent custom filtering is a service available for extra payment.
Our speedtest.retn.net server enables bandwidth testing up to 1Gbps. It is located in Moscow at RETN PoP Maryina Roscha connected with a 1Gbps uplink. You can also test your connection speed using software called “iperf” available at speedtest.retn.net.
It’s commonly known that connection speed of one TCP session significantly depends on the roundtrip time (RTT). The higher RTT is, the lower is the result for that TCP session.
You can find a TCP Throughput calculator here.
When measuring connection speed with the help of iperf, you should conduct at least 10 TCP-sessions to achieve appropriate results:
iperf.exe -c speedtest.retn.net -P 10
Alternatively you may use UDP protocol for the speed test: iperf.exe -c speedtest.retn.net -u
Content filtering is applied on the customer service interfaces and depends on local government acts. For example, RETN customers in the Russian Federation are denied access to particular URI on the specified IP addresses listed in Unified Registry of Forbidden Resources. Such limitation cannot be considered as a flaw in service quality level.
