I'm posting an update to this email thread since I was asked to keep other XMPP operators posted with any updates on the investigations.
I've been in contact with several owners of federated networks, and performed debugging sessions which hasn't really lead to anything conclusive. None of the cases that I've gone through seems to have been related to the intermittent problem reported here though, and I'm still open to debugging these issues further. The people I've been in contact with have either had configuration issues on one or more of their domains, or experienced problems with connecting to us in the past but not currently. Basically, if you have noticed a regression in your services since a few months ago where you are no longer able to setup a connection to us, feel free to contact me and I'll look into it. We'd like to find any regressions in our server-to-server code to provide a better experience for other federated XMPP networks. You can also email us at x...@google.com , which is an email alias for several Google engineers working on our XMPP infastructure. - Björn, Google On Thu, Feb 23, 2012 at 3:50 PM, Juan Pablo Carlino <jpcarl...@gmail.com> wrote: > Hello, > > during the last three months i've experienced an intermittent problem to > federate with google.com.
