Dear GNPS/GNPS2 team and community,

I would like to ask whether there is a known issue with resolving USIs originating from Metabolomics Workbench datasets.

Until about a week ago, these USIs could be successfully opened in Spectrum Resolver (e.g., for viewing mirror plots and inspecting MS/MS spectra). However, they currently appear to be unavailable or fail to resolve.

USIs from other repositories (GNPS/MassIVE, MetaboLights, Norman, etc.) do not seem to be affected and work as expected.

I would appreciate it if you could let me know whether this is a known issue, a temporary service interruption, or something specific to my usage.

Below are two example USIs that currently fail to resolve on my end:

Example 1:
mzspec:ST003880/Control_L5S1TC001_NP_pos_neg_01.mzML:scan:3851
Example 2:
mzspec:ST003189:17.mzXML:scan:526

Thank you very much for your time and for maintaining such an invaluable resource for the community!
