I agree and think that at least a mailing post here and on wikidata-tech
would've been great to make sure everyone has the chance to know what's going on Well, we only noticed what was up due to this email! Take a look at https://phabricator.wikimedia.org/T119915
So you can always get an overall view of the query service at https://grafana.wikimedia.org/dashboard/db/wikidata-query-service Key here for your issue would be the lag graph in the middle right. This is generated using the following query: SELECT * WHERE { http://www.wikidata.org schema:dateModified ?y } Which gives you the last modified date for the data stored!

Nice that the SPARQL service is upgraded. We noticed something was going on and terminated our bots to wait for more stability.
- Is that stability now reached?
- Is there some sort of flag-mechanism, that would indicate if the SPARQL
endpoint is stable, being upgraded or had change in state?
The SPARQL endpoint is core to our efforts in genewiki's ProteinBoxBot, for a spectrum of reasons. (e.g. concept resolution, identifying data inconsistencies (an item on a gene and protein being incorrectly merged), getting precision and recall numbers on included data sources, etc) Whenever there is an issue, we usually take a step back and retry later. However, this is based on trial and error. It would be quite convenient if we could use a flag-mechanism to decide if we can start or if already started we need to terminate.
Can we do this? Advise on different approaches would be also appreciated.

Hi!
is it me or is the SPARQL service very slow right now?
I've upgraded it yesterday to Blazegraph 2.0 and it looks like there was some glitch there. I've restarted it and now it seems to be fine. I'll be watching it and see if it repeats.
