Considering this project, I cannot find the boundary up to which the convergence has currently been verified. Can anyone provide the answer?

The WU in progress with the highest number is 6,415,879,838,212,923,850,752. However, that does not mean all numbers up to that have been checked. Each WU checks approximately 53 trillion numbers, but they aren't necessarily completed in order. When people abort them abandon the project, or they timeout or error out, they get resent to another computer. That sometimes happens half a dozen times before a WU gets completed. With 271K WUs in progress, it is impossible to give an exact answer.
