M1 Services not working since the past few days

I’m able to use the M2 & M3 services properly. But since the past few days M1 services are constantly giving me this response.

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">\n<html><head>\n<title>503 Service Unavailable</title>\n</head><body>\n<h1>Service Unavailable</h1>\n<p>The server is temporarily unable to service your\nrequest due to maintenance downtime or capacity\nproblems. Please try again later.</p>\n</body></html>

It was working earlier. Please look into it.

@IntegrationSupport - can you please look into Akash’s request asap - we are getting delayed for the certification.

@Ramandeep1- who can take up this issue of M1 server non responsiveness?
