While I'll still believe it when the money is in my account, they have posted this on their website:

Colombo 14th May 2020, 1155 hours - Sri Lankan Time: Due to the flight cancellations arising due to the COVID 19 pandemic, our refund volumes have increased significantly, exceeding 10 times the usual volume.
We have taken a number of steps to increase our refund capabilities by utilizing additional resources and tools which have significantly increased our daily refund processing capabilities. We intend to complete the current backlog of refunds by August 2020.
SriLankan Airlines also wishes to inform its valued customers that for the tickets purchased online, the refund process will take additional time since the Airline will require to liaise with Internet Payment Gateways (IPGs) in the remittance of money for refunds.
I don't expect UL has massive resources available, or the best IT systems, to deal with all these refunds quickly.
