Yes, great question, [ Tarik ]. So if you think about what happened in Q1, as I mentioned in my prior remarks, we had transformer issues at third-party hosted sites and we had a utility line maintenance that was done that shut down one of our sites for a short period of time, and then we had weather events. All of these are exogenous factors. If you think about when you own and operate sites, you look to do things like standardize equipment across sites so you have standard operating procedures, you also have spare parts for everything you're doing. One of the challenges with the Ellendale site were transformer issues, where some of the transformers that were installed could not operate at their stated spec. And so, as those transformers started to fail, they had to be replaced and/or modified. And had we built that site, we most probably would not have used Chinese transformers but rather transformers of higher quality that would operate within spec. So again, over time, as more and more of the sites that we operate at come under our own control, I think we'll see uptime continue to tick up and we'll see performance improve. When you think about just operating efficiencies, again, stripping out the third-party hosting provider dramatically impacts your cost because you're stripping out some of these built-in margins. And we also begin deploying our immersion technology. The 2PIC immersion technology does a number of things. For one thing, it increases the -- essentially, the lifespan of miners because these miners that traditionally would be air cooled in many sites essentially have to be serviced every 30 days, they have to be cleaned, filters have to be changed, fans have to be replaced, and the mechanical load at the sites is higher. Using 2-phase immersion, you don't have a lot of those issues. We have immersion systems that have run for months without having to be serviced at all. And so, that reduces the overhead at the site, which reduces your operating cost, makes you more efficient, increases uptime. And the other advantage with 2PIC immersion is that, you become fairly immune from heat waves because, at the end of the day, the liquid in this tank is boiling, which means that it's likely to be hotter in the tank than the ambient temperature would be. So that makes heat much less of an issue, especially in places like Texas and in the UAE, for example. And if you look at our site in UAE, that site operates with 99.8% uptime. And this is in an environment where the ambient temperature is over 100 degrees and humidity is well into the 90% range. So I think that's a great example of how our sites operate more efficiently and more effectively when they're under our control.
