21-11-2017 HW issue affecting some S2S hindcasts availability
We have recently experienced a couple of hardware incidents with tape volumes becoming damaged:
During October 2017, a large proportion of hindcast (enfh), perturbed forecast (pf), single level data (sfc) was not available from tape. Data cached on disk would not be affected, but data from tape would fail. This problem was resolved on 8th November 2017.
From beginning of November 2017 until 21st November, half of the hindcast (enfh), perturbed forecast (pf), pressure level data (pl) are not available from tape.
Unfortunately, requests for data from damaged tapes were blocking access to all S2S data. In order to prevent blocking all S2S service via the WebAPI, we disabled access to (2) during the specified period. We apologise for any inconvenience.
As of 14:30 UTC access to all hindcasts has been restored.
