[Sources: Microsoft Tightens Oversight of New Neocloud Data Center Projects by IREN, Nebius, etc.] According to Bloomberg, sources familiar with the matter revealed that Microsoft is tightening oversight of some data center projects by neocloud companies such as Nebius, IREN, and Nscale, abandoning projects deemed risky, and internally discussing whether to sign new cloud service agreements. The sources said that some recent issues are related to the cabling of a data center being developed by IREN in Texas, USA. The two parties negotiated revised timelines last week, and the project's completion date may be delayed by weeks or months. A Microsoft spokesperson stated that adjusting plans based on circumstances is normal practice in managing large infrastructure projects; IREN declined to comment. IREN transitioned from cryptocurrency mining to the AI field in 2023. Shares of both IREN and Nebius fell by about 20% on Thursday.
