Update - The issue is cased by a suspected break in an undersea cable but our ISP are keeping us updated with resolution progress. In the meantime, latency to Japan-based services (GCC) is much improved - response times from Singapore are back to normal and those from India are significantly reduced from their peak on 26th/27th December.

Monitoring - One of our ISPs in Japan is experiencing latency issues which are affecting connectivity from some locations. Customers in Singapore and India may experience high latency or timeouts when connecting to GCC. Certificate issuance may take longer than usual in some cases.
GlobalSign's Infrastructure team have rerouted traffic between our Japan and Singapore data centres to reduce any delays in issuance, and are communicating directly with the affected ISP, to ensure the issue can be fully resolved for customers in India and Singapore.
