In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Issue from INFN-T1:
During the past week-end an incident involving connectivity to the INFN Tier-1 occurred.
On Saturday July 5, 2008 at 03:29 (all times are local) a 10 Gigabit/s interface on one of the Tier-1 core switches started flapping. This interface is part of a bundle of 4 10GE interfaces. Although the flapping should not in itself have caused much disturbance to the network infrastructure, the effect was intermittent connectivity to various sets of computers across the Tier-1.
Problem troubleshooting started immediately, with system specialists looking for possible causes of the problem already in the morning of Saturday July 5, 2008. What rendered detection of the fault not immediately obvious was that no traces of the flapping were recorded in the log files of the core switch actually exhibiting the problem. On Sunday night an official EGEE broadcast message was issued.
On Monday July 7, 2008 the priority for the replacement of the faulty network card was escalated to the highest possible level to the switch vendor. At 17:00 the faulty network card was replaced, and the network was operational again. A fallout of the network problem was that several systems were stuck and had to be rebooted.
On Tuesday July 8, 2008 at 11:00, during certification of all INFN Tier-1 subsystems and services, some other network problems were detected. At 12:30 the cause of these problems was identified through log messages in a faulty core switch management card, which caused among other problems random packet loss. Another ticket was opened with the switch vendor, and in the afternoon a replacement management card was received. The replacement of the card and a related operating system upgrade to the core switches finished at 22:00.
In the morning of Wednesday July 9, 2008 all network, storage and farm subsystems and services were checked and certified as ready for operation. But since the INFN Tier-1 was still in downtime, the decision was taken to replace the the broken component of the electrical switch mentioned above on Thursday July 10, 2008.
Now all services (network, farming and storage) are up and running.
[Northern]: Estonia: On the whole period we had the site mostly on downtime because there were odd errors with job submission that we were unable to understand. There is a ticket open in GGUS with number 38270, however the responses we have gotten have not been useful. This is not the first time that GGUS has proven to be useless for days/weeks for non-trivial errors and is causing serious reduction in reliability for the site.
