Hi Jhaveri, Darshan,

Thanks for reaching out to Microsoft Q&A.

can be related to several underlying causes, given that you mentioned a similar issue occurred recently in the East US region with ADF failures or delays, it's possible that the current situation might be linked to ongoing or recurrent service disruptions in that region. Always keep a tab on service health using the URL below or even create an alert if needed. I am also mentioning few common reasons which you might check as well.

• If there is a spike in usage within the East US region, the resources allocated to your Synapse workspace might be constrained, leading to queuing of pipeline activities.
• There could be configuration issues in your Synapse Pipelines that cause excessive queuing. For example, dependencies on long-running activities or concurrency settings might lead to bottlenecks.
• Check network configurations, including firewall rules, virtual network (VNet) setups, or other connectivity options.

If nothing worked, create a service ticket with azure support.
