Friday, 19th june 26 - almost all day been experiencing lags with simbrief, including using the webpage and running it in my sim. Charts work fine, but loading the flight, in both Fenix A320 and iniBuilds A350 into their respective FMGCs and EFBs has issues. sometimes it fails so i have to request it again, and sometimes it takes 15-20 seconds to load it.

Anyone else having same problems? Could it be on my end?

Hi, there are no current server issues, and no other indications of slowdowns affecting other users.

It’s possible that the problem is on your end, please try restarting your router/modem and PC to see if that helps.

Best regards,

Did nothing, it seems to be fine today. I flew a “long haul” overnight, and I haven’t even restarted the sim and I notice no issues today. But yesterday, whole. day. long. I think I did 3 or 4 flights, including the transatlantic last night every single one had some lag fetching the flight plan details.

As Derek mentioned, we’re not seeing any abnormal behavior with SimBrief. In fact, SimBrief has a network stats page which shows if services are being disturbed or disrupted.

If latency is noticed, it must be upstream of your network connection, unfortunately.
