New password retrieval policy (aka: NOPE)

Posted by – September 4, 2014

flattr this!

Today our steering committee took the following decision:

Unfortunately, there is no way for the server administrators to check if
you are actually the person who registered a given account – the only
information you supplied when registering was the Jabber ID and your
password.

Therefor we won’t be giving out new passwords for lost ones anymore.

New hardware, new colo

Posted by – July 1, 2014

flattr this!

We’re going to move the jabber service to newly bought hardware tonight, this is attended with moving to a new colo site.

New hardware: Supermicro X9DR3-F, 32GB RAM, Dual Intel(R) Xeon(R) CPU E5-2609.

New colo: Nessus, Vienna/AT

New IP addresses: 146.255.57.229, 2a02:1b8:10:31::229 (just in case your DNS caches the old IPs too strictly)

Sorry if you lost your bookmarks and other information stored in pubsub, but the server didn’t want to start with them being prefilled.

Encryption required on c2s and s2s links

flattr this!

We’ve now finally enabled required encryption on s2s links, so if you’re unable to chat to and see your friends at Google Talk or google-enabled domains, that’s the reason.

Heartbleed?

Nope, we’re not affected. KTHXBYE.

Downtime today (colo power supply maintenance)

Posted by – March 14, 2014

flattr this!

We’ll be shutting jabber.ccc.de down for at about 10:45 CET today since there are planned maintenance works at our colo’s power supply.

These might last a bit too long for our UPS to cope with the outage.

s2s enquiring encryption (at least) for today

Posted by – January 4, 2014

flattr this!

As mentioned in https://github.com/stpeter/manifesto, we changed the server’s config to require TLS for the server-to-server links.

This might (and possibly will) destroy communications with your friends at Google Talk, since up to now they (Google) do not support TLS on their s2s side of XMPP.

Discussion about this test day can also be found at the XMPP operators list: http://mail.jabber.org/mailman/listinfo/operators

Roster Versioning temporarily disabled

This morning we temporarily disabled Roster Versioning (XEP-0237) since it wasn’t working and only threw client errors when requested.

Recent downtimes

Just in case you haven’t noticed: We’re experiencing quite a nasty bug (maybe, not proven yet) inside ejabberd which leads to a) ejabberd eating all of the available memory and b) afterwards having one thread run at 100% CPU. At this time, ejabberd stops forwarding packets and accepting new connections.

Just to keep you informed.

P.S.: We do have a Twitter account that might (!) have more up-to-date information than you can find in this blog: @jabberccc.de

New SSL certificates deployed (which fixed S2S, too)

Some hours ago we deployed new SSL certificates – those fingerprints can be found at the SSL page.

Luckily this fixed the S2S issues we had with some other servers, too.

Yup, we’re down

And since some of use are on holiday and IPMI isn’t working this is about some other entities to help us more.

FYI: We might move to a different hardware this month, so the not-so-working remote console will be fixed.

!Recovery: Memory usage right before...
