title1006-0102-2018 HW issue affecting some S2S hindcasts availability

We have recently experienced a hardware incident with a tape volume becoming damaged:

  • From 31 December 2017, half of the hindcast (enfh), perturbed forecast (pf), pressure level data (pl) are not available from tape. Note data cached on disk is still available.

Unfortunately, requests for data from a damaged tape are blocking access to all S2S data. In order to prevent blocking all S2S service via the WebAPI, we have disabled access to that specific dataset (reforecast, perturbed forecast, pressure level) until the problem is resolved.. We apologise for any inconvenience.

As of 19:00 UTC access to all hindcasts has been restored.

title21-11-2017 HW issue affecting some S2S hindcasts availability

We have recently experienced a couple of hardware incidents with tape volumes becoming damaged:

  1. 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.
  2. 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.
