Unpaywall data feed issue (resolved)

[Casey Meyer]

Hi all,

I sent an email to data feed subscribers but am posting here in case I missed somebody. If you do not subscribe to the Unpaywall data feed (which requires an API key), you have nothing to worry about. Here is the update:

We recently learned about an issue occurring since early February 2023 where two weekly updates and 10 daily updates were skipped and not created. That means if you are syncing your data from the weekly or daily feed, you are very likely missing those updates.

The issue is resolved and the missing files have been restored. Specifically, these are the dates that you would need to ingest to get your data caught up:

Weekly feed (https://api.unpaywall.org/feed/changefiles?interval=week)
2023-03-08 to 2023-03-20
2022-02-18 to 2022-02-22
2023-02-14 to 2023-02-20

Daily feed (https://api.unpaywall.org/feed/changefiles?interval=day)
2023-03-11
2023-03-01
2023-02-28
2023-02-27
2023-02-26
2023-02-25
2023-02-24
2023-02-23
2023-02-14
2023-02-13

Let me know if you have any questions!

Thanks,
Casey
