vLib downtime due to scheduled power outage

Due to a scheduled power outage vLib will be unavailable on Wednesday, 17/11/10, from 6 am onwards.

As a a high number of services will be experiencing a downtime, systems will be initialized successively after the outage.

We have done our best to prioritize the start of vLib, however, we are unable to give any more precise point of time when vLib will be available again but between 9 and 12 o’clock in the morning.

MPG/SFX services should be available without interruption.

More info see GWDG News.

We apologize for any inconvenience.

vLib outage ahead (Wednesday 8 September)

The GWDG currently undertakes some necessary construction work in their server room and the vLib server need to be moved to a new location in this context. Therefore, our hosting partner scheduled a downtime for the vLib portal on Wednesday between 07:30 a.m. to approximately 12:00 a.m. We apologize for any inconvenience.

Update from 1 pm: Server restart will be delayed by two hours at least.

vLib server down (Tuesday 24 August)

Unfortunately, the vLib portal is not running at the moment due to server problems at our hosting partner. The responsible system administrators at GWDG work intensely to resume service as soon as possible.

We apologize for any inconvenience.

Update from 6 pm: The problems have been caused by a failure of memory devices. The system was restarted successfully in the meantime.

vLib Resource Types revised

Resource types have been revised.

The former resource types Factual Database, ePrint Server, and Subject Gateway are now generally typed as Miscellaneous.

Old links should redirect if defined for interfaces /start or /resource_type (more info on service interfaces).

A complete list of eBook-related resources is now available at http://vlib.mpg.de/start?type=Book%20Collection.

Hence the option eBooks has disappeared from the Special Content dropdown at http://vlib.mpg.de/start?srv=locate. Former deep links, for example http://vlib.mpg.de/start?special=ebooks, should continue to be supported if set up using the above service interfaces.

MPG/SFX scheduled downtime (Sunday 14 February, early morning)

In order to prepare an upcoming migration, the GWDG scheduled a few hours downtime for the MPG/SFX server on Sunday between 01:00 a.m. and 06:00 a.m.

Please be aware that MPG/SFX services will be unavailable during that time, while the upcoming system is synchronized with the MPG/SFX server in production.

On Wednesday, February 17, after thorough testing, the new system will be switched to production during our regular maintenance hours, which will involve another short downtime.

!! PLEASE NOTE: Switch to production was re-scheduled to take place on Thursday morning, February 18, between 8 and 9 a.m. Apologies for the short notice. !!

We apologize for any inconvenience.

Problems with Safari Books Online

Unfortunately, we noticed several problems with accessing the Safari Tech Books collection over the last days:

  1. The MPG/SFX server sometimes fails to redirect requests to the correct entry page, see example.
    Solution: Prefer the link offered by the "MPG eBook Index" as this seems to work much more reliable.
     
  2. Not all book content loads correctly if you select a particular book section from the table of content, see example.
    Solution: Try to switch to the HTML view instead by clicking the new icon from the Safari tool bar, i.e.
    safari tool bar

Note: We and the Safari support are aware of these problems and hope to solve them soon!

MPG/SFX: Unexpected outage solved

Today, the MPG/SFX server was not available from 12 a.m. to 3 p.m., due to a crash of the SFX database. Meanwhile our hosting partner managed to restore the database from the backfile and restarted the service successfully.

We are sorry for the inconvenience (and will try our best to get rid of all the bad karma 😉
