Issue with FDSN Service: Missing Waveform Data (2019–2022))

Hello,I am a research intern at CRISiSLab.Recently, I attempted to download waveform data using the FDSN service with the following code:

from obspy.clients.fdsn import Client
from obspy import UTCDateTime

start_1 = “2020-01-01 00:00:00”
starttime = UTCDateTime(start_1)
endtime = starttime + 600 # 600 seconds
client = Client(‘RASPISHAKE’)
waveform = client.get_waveforms(‘AM’, ‘R24FA’, ‘00’, ‘EHZ’, starttime, endtime)

Previously, this code provided data from 2019 to 2022 without any issues. However, when running it recently, only data from 2022 onward is available. My dataset spans 2019 to 2024, so the earlier data is crucial. This discrepancy raises concerns about data accessibility.

Is there a way to retrieve the missing data from 2019–2022?
