@wyoung I don't have access to the actual CIFS host machine, just indirectly through the mounted drive. This is done automatically by Azure and it's mounted on /home (any data outside /home is not persisted). The actual app service host and CIFS host are both on the same data center for sure. For reference, the app service code is located on /home/site/wwwroot and the sqlite database on /home/site/wwwroot/data). This is how the CIFS volume was mounted (anonymized the output): <pre> mount -l -t cifs //10.0.AAA.BB/volume-CC-default/aaaaaaaaaaaaaaaaaaaa/bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb on /home type cifs (rw,relatime ,vers=3.0,sec=ntlmssp,cache=strict,username=dummyadmin,domain=RDcccccccccccc,uid=0,noforceuid,gid=0,noforcegid,addr=10.0.AAA.BB,file_mode=0777,dir_mode=0777,nounix,serverino,mapposix,mfsymlinks,noperm,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1) </pre>
