Identified - We've identified the cause and are implementing a fix.
Mar 12, 16:51 UTC
Investigating - Since Friday 8th March, we have received some reports of inconsistent or unexpected Cited-by counts. The /works endpoint of our API is intermittently returning incorrect Cited-by counts in a small number of cases (in the fields is-referenced-by in JSON and crm-item name="citedby-count" in XML). The incorrect values are very large, e.g. 842,611,252. Sorry for the inconvenience; we are currently investigating and trying to replicate the problem and will fix or update here ASAP.
