Dotsrc is now hosting Tor exit nodes!
Thanks to DeiC for being LIR and upstream, and to Henrik Kramselund for letting us use some of his IPv4 addresses.
More information about the relays can be found here.
Dotsrc is looking for IPv4 address space
Dotsrc have been running fast Tor relay nodes for the last couple of years. Last year we began testing if we could operate Exit nodes as well, and did so for about two months. The vast majority of exit traffic is of course benign, but there’s also some malicious traffic which our ISP wasn’t too happy about.
Since then we have had quite a few meetings and long email threads looking into possible solutions.

dotsrc have successfully moved to the new location
mirrors.dotsrc.org should be back up and running
We have successfully moved to new location and mirrors.dotsrc.org should be up and running. Please write us on staff@dotsrc.org if you do not think this is the case and we will take a look :)
Note that one of our virtualization servers still is down at the time of writing, see this post.
Thanks to Aalborg University for supplying us with one more server, assistance, and still accomodating us.
Below are some pictures of the move, we will spare you the details.

dotsrc are moving to a new location
The time has come for dotsrc to move our servers from our current server room at Aalborg University to a new one. The old locations had been decommissioned and were no longer maintained. Without adequate cooling, the servers have begun to behave rather strangely. Thus the relocation has been expedited.
We hope that all services are up and running again during Thursday afternoon.
Hardware failure on mirrors.dotsrc.org
ETA: Fixed
mirrors.dotsrc.org is unavailable, starting at aprox 2021-06-01T11:30+02:00. One of our HP D2600 disk enclosures had crashed, which took down the entire ZFS pool again.
Update 2021-06-03: Fixed by moving to a new location, see newer posts.
Hardware failure on mirrors.dotsrc.org
ETA: fixed
mirrors.dotsrc.org was unavailable for about 2 hours, starting at 2021-05-30T19:51+02:00 until it became available again at 2021-05-30T21:56+02:00.
One of our HP D2600 disk enclosures had crashed, which took down the entire ZFS pool.
Update T20:45+02:00: We’ll have a man on-site T20:45+02:00. If we’re lucky mirrors.dotsrc.org should be back online shortly thereafter. If the disk enclosure is completely dead, ETA is unknown.
Update T22:20+02:00: Thomas was able to fix the problem! We’re back online!

Hard disk failure resulted downtime
After a hard disk failure on one of our virtualization servers, the following services have been down since 2021-05-02 10:20:07:
- Website
- Tor relay
- LineageOS build server
- OpenStreetMap tile server
As a temporary measure the website has been moved to Gitlab pages until the issues have been resolved.
We Have Recieved New Network Adapters
Thanks to our sponsor BrightStar Systems
BrightStar Systems sponsored 2 Intel X520-DA2.
We have been having some trouble with our current network cards (we are currently running at 1x10G) and will use these to replace them (restoring our previous 2x10G) :)
Statistics for Web Traffic
WIP statistics for HTTP and HTTPS requests
Since September we have been working on collecting usage statistics for our HTTP and HTTPS mirror traffic. This will give insight into which folders and files are accessed often.
We currently collect the following values from each request:
- Path relative to mirrors.dotsrc.org
- Downloaded size
It is implemented with the following nginx log pattern:
log_format logserver '$bytes_sent $uri';
More info can be found here.
Our Tor nodes no longer accepts exit traffic
Our ISP DeiC has decided to ban hosting of Tor exit nodes directly on the Danish national research and education network.
All hope is not lost - we’re still working with DeiC to find a solution.
In the meanwhile, please consider running a Tor node yourself (exit if you can, non-exit otherwise). Check out the Tor Relay Guide to get started.
