Heya!
We've had a couple of incidents with the BobRTC service and bugs causing a service crash. These happen to be normal with new experimental software. It's not scammers bringing down our service but rather concurrency bugs when more than one thing is trying to do an operation at once, usually on a resource that can only handle one thing at a time or it's looking at data that is in the middle of being refreshed, so the jobs that are trying to get the data were not told to wait until the data is refreshed and so they got bad data.
So far we've found 3 of these issues and have written patches for them. There may be more of these little gotchyas in the software but we have a process in place to extract where the fault occurred and to get a dump of memory so we can see what was going on at the time the fault happened so we can code a fix.
It's all perfectly normal. If a crash happens please let the mods know in Discord.
