ALeRCE LSST services will undergo maintenance on Thursday April 16 2026 15:00 UT. Downtime is expected to last until same day 21:00 UT at most. During this time, users may experience patchy access to LSST data stored in the ALeRCE database through TAP, API, python client and web interface (lsst.alerce.online). ALeRCE ZTF services will not be affected.
We will inform the end of the maintenance period as a reply to this announcement.
