數碼移民潮觸發之後，通訊軟件Signal突然爆紅，大批WhatsApp用戶一窩風下載，但自昨晚起，有新用戶發現未能正常收發訊息。
Signal在官方Twitter公布最新情況，承認遇到技術問題，正努力盡快修復。
Signal又指今個星期，每日都以破紀錄的速度增加伺服器容量，感謝用戶耐心等待。
直至香港時間今早（1月16日），Signal表示仍在努力盡快提升容量，以處理高峰流量。
We are still working as quickly as possible to bring additional capacity online to handle peak traffic levels.
