# Run listed as Uploading to Network or BaseSpace on the NovaSeq 6000

Universal Copy Service (UCS) is responsible for uploading a run to either the network drive or to BaseSpace Sequence Hub (BSSH). If a run is stuck in uploading even though it is completed on the instrument, it is likely due to a network connection issue.

To troubleshoot this, follow the steps below.

* If a run is in progress, close and reopen the Process Management tab to refresh the status.
* If a run is not in progress, power cycle the instrument and re-open the Process Management tab to see if the status changes.
  * For more information, search for Knowledge Base article **How to Power Cycle the NovaSeq 6000 System.**
* If the issue persists after the power cycle,
  * For run transfers to a network drive:\
    \- Confirm that the network drive is mounted and connected. Reconnect if the network drive is disconnected and refresh the Process Management page in NovaSeq Control Software.\
    \- **NOTE**: If the network cannot be brought back up, run data can be manually copied from the CE Z: drive location (Z:\outputfolder\[run folder]), using the USB3 port to an external hard drive.
  * For run transfers to BaseSpace:\
    \- Confirm internet connection has not been interrupted.\
    \- Confirm internet upload speed (a minimum of 200 MB/s is required per Instrument/System for BSSH upload). Slower speeds may prevent successful uploads.
* If the network drive is connected and the internet connection is uninterrupted, stop and restart Universal Copy Service. For more information, search for Knowledge Base article **How to stop and restart Universal Copy Service manually on the NovaSeq 6000.**
* If the upload does not resume after restarting Universal Copy Service, contact [Illumina Tech Support](https://www.illumina.com/company/contact-us.html#/united-states/technical-support) for the next steps.
