ALeRCE LSST and ZTF services will undergo maintenance on Thursday July 2 2026 17:00 UT. Services are expected to be back by the same day at 21:00 UT. During this time, users will not be able to access to LSST and ZTF data stored in the ALeRCE database through TAP, API, python client, SQL queries and web interfaces (lsst.alerce.online and alerce.online).

We will announce the end of the maintenance period as a reply to this topic.
