2021-07-31 IRC network freenode was classified as historic

freenode, that largest IRC network for many years seems to have a new authorization mechanism. Our crawler is not able to establish a connection any longer and a nickname registration at was not successful. – We couldn't log in :( There was a problem connecting :( – At the moment I don't see another way to classify freenode as historical. I will check that again in a few days, but it may be that this status remains.

2015-02-14 Filtering of Janus links...

IRC networks that use Janus to establish links to channels of other IRC networks will be marked as mavericks in future. That means that they don't appear in the top 100 list and their channels can't be found via IRC search.

This was a long-needed step to filter channel duplicates and to reduce abuse of reported user numbers.

Website was moved to another/better hardware.
2014-06-18 Week of server outages...'s IRC statistics are based on two servers. First server serves as data collector for most of the known IRC networks. Second server is mainly used for database and website. Yesterday website was down because of a broken power supply on server two. Power supply was changed and website restarted its work. Today data collection was temporarily interrupted, because load on server hardware (second server runs as virtual machine) was too high. Virtual server was moved to another hardware and now everything should work again... for a while. *grin*
2014-02-17 Server outage...

Main collection server was down since Friday. Unfortunately I was on vacation a few days. So I haven't noticed the outage until today. Now everything is running as usual again.
