Why are there ObjectID gaps in Survey123 data?

Hi - I have a Survey123 that has been public for over a month and received over 5,000 submissions. Until today, the ObjectIDs were consistent and in order (i.e. 1 to 5851). However, there was a 40-minute time period this morning during which 14 OIDs got skipped (never existed in the data), with a few that came through in between (we are missing OIDs 5852-5857, 5859-5863, and 5870-5872). Is there an explanation for this? Without having any jumps in the OID range until now it seems concerning, as if somehow those entries were lost or not properly transmitted through the AGOL servers. If jumps in OIDs are to be expected, why would this only happen now after a month of consistency? Since the issue this morning, the OIDs have been populating in order, as before.

Thank you!

Hi Anneka,

Do you know exactly what date and time the issue occurred? If so, please contact Esri Support and they will open a case to investigate if there was any interruptions or down-time during that exact time and if it affected your ArcGIS Online organization.

It is not expected there would be any gaps in ObjectID unless the data has been deleted after it was successfully submitted, or there was an issue with the server at the time.

Regards,

Phil.
