The recent SLA is ~99.6%. Our tech team monitors outages 24/7.
In case you experience an unusual failure / timeout, you can always reach us by email (usually replied within 1 business day). If your average monthly pay > $500, e.g. you get a Dedicated Line, you can also reach us by whatsapp (usually replied within 2 hours during business hours).
We have customer support in San Francisco and Korea. The business hours apply to our coworkers in these two places.
