Starting last Tuesday, I've been getting a persistent error running the runUpdate.sh script from the Wikidata stand-alone facility.

Example:

06:34:20.402 [update 6] WARN org.wikidata.query.rdf.tool.Update - Contained error syncing. Giving up on Q13873706

org.wikidata.query.rdf.tool.exception.ContainedException: Unexpected status code fetching RDF for https://www.wikidata.org/wiki/Special:EntityData/Q13873706.ttl?nocache=14975...: 429 at org.wikidata.query.rdf.tool.wikibase.WikibaseRepository.fetchRdfForEntity(WikibaseRepository.java:267) ~[wikidata-query-tools-0.2.3-SNAPSHOT-jar-with-dependencies.jar:na] at org.wikidata.query.rdf.tool.Update.handleChange(Update.java:474) ~[wikidata-query-tools-0.2.3-SNAPSHOT-jar-with-dependencies.jar:na] at org.wikidata.query.rdf.tool.Update.access$0(Update.java:472) ~[wikidata-query-tools-0.2.3-SNAPSHOT-jar-with-dependencies.jar:na] at org.wikidata.query.rdf.tool.Update$1.run(Update.java:370) ~[wikidata-query-tools-0.2.3-SNAPSHOT-jar-with-dependencies.jar:na] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) [na:1.8.0_131] at java.util.concurrent.FutureTask.run(FutureTask.java:266) [na:1.8.0_131] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [na:1.8.0_131] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [na:1.8.0_131] at java.lang.Thread.run(Thread.java:748) [na:1.8.0_131]

Does anyone have an explanation for this?

Thanks,
