There appeared to be a problem earlier today with POST type web requests timing out. A POST request is used whenever you click a button in the web-interface. A small number of users, all on LAN or DSL connections, in completely different parts of the world were affected by this.
We’re not too sure what caused this problem, but it seemed to be low-level network issue related to MTU values in the TCP/IP protocol. We have not yet determined whether the problem occured in our network, or on an external Internet router.
Update:Our data centre has found the problem, and reolved it. It was due to an MTU problem at a peering point.
