Whitefiber went public on the NASDAQ in August 2025, raising approximately $150M. The combined company ($WYFI and $BTBT) has a market cap approaching $1B. Bit Digital recently announced a North Carolina datacenter that can expand from 24MW to 99MW, a large augmentation to their existing footprint in Montreal, with the intention to host more AI customers. In the past the company has mentioned LOI’s for 288MW, and they have publicly announced contracts for 4,096 H100, 1,040 H200, and 464 B200. You can read more about companies like this, and their expansion plans in our [datacenter model](https://semianalysis.com/datacenter-industry-model/). In our testing, Whitefiber’s networking was within the reference numbers if not slightly better for some message sizes. In terms of other aspects, we were sadly disappointed and did not match the same quality as their networking. we were given a Slinky cluster, with access to both the slurm and kubernetes layer. Unfortunately, neither of them worked. Initially, slurm was inaccessible from a remote machine, with lots of negotiation required to make it work. Meanwhile, at the kubernetes layer, nothing could be scheduled since slurm-bridge was not configured, and all GPU resources were taken by slinky. Eventually, we got a jump box working to get into the slurm cluster, and found the typical slinky footguns: no git, vim, nano, python, or sudo permissions to install software. Cluster dashboards were long and detailed but missing important metrics about jobs. No active or passive health checks could be found. We were given access to dashboards for clockwork and trainy, neither of which were explained or documented, and were therefore not useful in our testing. Whitefiber has clearly made investments in their AI cloud offering by hiring a large team of consultants, integrating a custom interconnect to replace NVIDIA, and buying every piece of software pitched to them. Unfortunately, they are held back even from the bronze category for lacking a basic security attestation from a third party auditor, such as SOC 2 Type I/II or ISO27001. We believe that by ClusterMAX 2.1 or ClusterMAX 3 if Whitefiber gets a basic SOC2 Type I compliance in place and fixes their SLURM/Kubernetes orchestration, they would find themselves in at least the bronze tier. --- Other Underperforming tier providers: - IREN/Iris Energy: https://www.clustermax.ai/cloudreview/irenirisenergy - Hydra Host: https://www.clustermax.ai/cloudreview/hydrahost - FarmGPU: https://www.clustermax.ai/cloudreview/farmgpu - DeepInfra: https://www.clustermax.ai/cloudreview/deepinfra - Dstack Sky: https://www.clustermax.ai/cloudreview/dstacksky - PaleBlueDot: https://www.clustermax.ai/cloudreview/palebluedot - Hyperbolic: https://www.clustermax.ai/cloudreview/hyperbolic - Aethir: https://www.clustermax.ai/cloudreview/aethir - Akash Network: https://www.clustermax.ai/cloudreview/akashnetwork - Salad Cloud: https://www.clustermax.ai/cloudreview/saladcloud - Clore: https://www.clustermax.ai/cloudreview/clore - Mithril/ML Foundry: https://www.clustermax.ai/cloudreview/mithrilmlfoundry - GPU.net: https://www.clustermax.ai/cloudreview/gpunet - Massed Compute: https://www.clustermax.ai/cloudreview/massedcompute - Exabits: https://www.clustermax.ai/cloudreview/exabits - Sesterce: https://www.clustermax.ai/cloudreview/sesterce - E2E Networks: https://www.clustermax.ai/cloudreview/e2enetworks - OVHcloud: https://www.clustermax.ai/cloudreview/ovhcloud - Dihuni: https://www.clustermax.ai/cloudreview/dihuni - Akamai/Linode: https://www.clustermax.ai/cloudreview/akamailinode - HETZNER: https://www.clustermax.ai/cloudreview/hetzner Full ClusterMAX 2.0 + 2.1 index: https://www.clustermax.ai/cloudreview Full LLM dump of all reviews: https://www.clustermax.ai/llms-full.txt
