[bioontology-support] Biomedical Ontology down?

Hello Allan (and everyone),

We strongly regret these outages; they are not planned, and we are not yet sure of the root cause(s).

We received similar complaints on the email list during that period, and several from other REDCap users, but we do not believe that REDCap use is having a signficant impact on system performance.

With respect to these particular outages, we have had discussions with a number of particular users who have been making large numbers of requests to the system, because for some reason over the past 10 days loads seem to be unsustainable, whether strictly due to the numbers of requests, or other interactions, we are not sure. We continue to instrument and troubleshoot the system to give us better feedback on the issues, which are intermittent as you note.

While we appreciate very much REDCap's inclusion of BIoPortal as a service, we have noted previously that BioPortal is a research service, and can only be kept available on a best-effort basis unless production Quality of Service levels are negotiated. (See for example

We will notify the list when we have more definitive information to share.

I manage a REDCap installation at University of Pittsburgh and we use the ‘auto-suggest functionality for searching biomedical ontologies’.

Several of our users contacted us last week with complaints of the biomedical onotology search being down, the service seemed to come back up the next day. It seemed to go down again on Friday and they were unable to do any searches. One user has advised that this service is critical for their study.

Is there any reason for the outages? Are they planned? If so is there a schedule of planned outages? Or, is it possibly something on our end? Each time it’s been unresponsive I’ve tried to manually hit the URL but that times out.
