The landlord-provided IP connectivity provider | The landlord-provided IP connectivity provider is a Gigabit fibre line from Onega -> Exponential-E -> OpenReach [https://www.exponential-e.com/business-internet-leased-lines Exponential-E] . For support and queries we need to go through [https://www.onega.net/ Onega] / Landlord. See below for IP address information. Currently the line is set to provide 500Mbps of symmetrical bandwidth upstream and downstream via IPV4 and IPV6. Others in the building share the line but are not heavy users. | ||

The building is being serviced by a shared 500 megabit via [https://www.onega.net/ Onega] portioned out to various tenants in the building. The actual IP connectivity provider looks to be [https://www.exponential-e.com/business-internet-leased-lines Exponential-E] but we need to go through [https://www.onega.net/ Onega] / Landlord if there are any issues/questions. | ||
The connectivity is set to allow everyone in the building full access to the Internet at full speed (ie if you are the only user online then you should get close to 500Mbps up and down on a speedtest site). The line is subject to fair and legal use but as long as no one abuses the connection or monopolises it then you can basically fill your boots (or SSDs). A 3.5 Gbyte Debian ISO DVD will download in approx 3 minutes. Please note that you should not download copyright materials from the web / torrent sites (movies etc.) as these are traceable by IP and it's also not a nice thing to do (unless you've paid for them legally)... more seriously that could lead to being cut off on a three strikes basis which we don't want to risk. There is no external rate shaping or packet inspection done on traffic at the ISP level unless there is any odd activity / complaints. Ben from Onega also happens to be a London Hackspace member so we should get helpful service to any reasonable requests. If / when needed the line could also be upgraded to the full Gigabit, or indeed to 10Gbps connectivity but right now the marginal cost would not be worth it given historic and current observed bandwidth levels. | |||
