Sandbox extremely slow

adding screenshot > adding support email > [email protected] hello team, wasn't able to find an email to contact support, but for me the sandbox is performing extremely slow. the last response i received from the REST api provider was: {"messageKey":"error.internal.default","technical":"EsepCommand timed-out and no fallback available.","message":"Unexpected Error. Our technical staff have been notified and will look into the problem. We apologize for any inconvenience this may have caused you.","code":500,"name":"Unhandled Server Error"} which was around 430: EST. any insight would be greatly appreciated. cheers.
