Narrative:

On final; ATC advised windshear alert -30 knots at 200 feet; company in front of us reported windshear and advised 'going around'. We received a windshear alert and commenced a go-around. Several aircraft were forced to go-around leading to frequency congestion and concerns about fuel and diversion airports. Forecast weather did not require alternate fuel. Initially ATC sent us to hold with the expectation of getting right back into klas. As we entered holding; ATC said getting back into klas would be delayed with windshear and microbursts overhead. We attempted to ACARS dispatch with diversion plan; received 'no comm' message. Requested ATC clearance to ZZZ; we were given a heading and began setup and briefing for descent into ZZZ. We expected to land with 4;700 pounds of fuel. ATC later advised us that landing ZZZ was not an option as we were number seven in line due to other diverts. Controller suggested ZZZ1. We advised ATC minimum fuel and asked for and received vectors to ZZZ1. Field was VFR and we landed on runway X with 4300 pounds of fuel. Based on our fuel and available information; landing at ZZZ1 was the safest course of action. Once on the ground we worked with dispatch; the chief pilot in the operations center and local FBO to obtain paperwork and authorizations for return trip to klas.
