The New Website is Live

If You See This on

We finally migrated away from the old unmaintained PHP CMS. As you can see in the footer, we are now using Hugo to generate static pages. What is New for Visitors? RSS Thanks to Hugo and our theme, you can now get news via RSS. The icon in the footer links to the feed! Theme We are trying keep the spirit of the old site intact, but it seems none of us are super interested in frontend development. [Read More]

Maintenance window for

We are seeing so much traffic that it is necessary to upgrade the hardware hosting We'll be starting at 2020-02-18T08:00+01:00 (ISO8601), and we expect it to last up to three hours. To convert that to your local time run: date -d 2020-02-18T08:00+01:00 If you want to get an email from us before the next scheduled maintenance, please let us know. Update: Upgrade went well.

IPv4 problems

All dotsrc services were unavailable on IPv4 from around 2019-02-12 12:30 CET to around 16:00 CET. IPv6 traffic was unaffected.

The outage was caused by BGP hijacking of announced from an Iranian ISP.


At we just got our internet bandwidth doubled. Not because we needed the capacity, but we wanted the redundancy.
We now have two 10G uplinks. One to our ISP's (DeiC) router in Lyngby, and one to DeiC's router in Ørestad. Thanks to DeiC and AAU It Services for making this possible.

Dotsrc offline for 1 hour

Due to some problems at our ISP (DeIC), all our services, except our IRC-server which is hosted elsewhere, was unfortunately offline about 1 hour from 2018-04-06 00:05:07 CEST until 2018-04-06 01:15:07.

We apologize for any inconvenience.

Milestone reached: 100TB a week

The total amount of data we upload every week has just passed 100TB! On average this is more than 1.33Gbit/sec.
Traffic graph.

Our mirror service is the main contributer, which accounts for around 80TB.

The last 20TB is shared between our other services (OpenStreetMap, Tor and Usenet).


The dotsrc servers are now backed by a 10Gbit Internet connection, and on top of this, the mirror server ( ) has been upgraded to a vastly better server, equipped with a 10Gbit network card. This big upgrade would not have been possible without our sponsors. Big thanks to: DKUUG - for a big cash sponsorship. DeIC - 10Gbit Internet connection. [Read More]

Two new services and new mirrors

We now run a tile caching server for OpenStreetMap and are a part of their tile CDN. We are the primary server for tiles served to clients connecting from Denmark, so if OpenStreetMap feels 'snappier' (at least in Denmark) it is thanks to us. We also set up a tor middle relay. This is a non-exit relay, so it only receives encrypted traffic and passes it along to another relay. [Read More]
