Cross-Time-Zone Operations

Six nodes: use data to choose the closest, then workflows to choose the right one.

HopVM provides Cloud Mac nodes in Singapore, Tokyo, Seoul, Hong Kong, the US East Coast and US West. Three configurations cover all six nodes, for 18 regularly available combinations; the console returns live ordering results.

The node count is fixed at 6. The same region is not split into multiple marketing names, and cities outside the catalog are not described as available nodes.

Every order corresponds to one dedicated physical Mac. The service uses cloud-hosted Macs and physical nodes, not virtual machines. All nodes operate normally 365 days a year.

Six Node Runbooks

Geographic distance is the starting point, not the only criterion

Start with the network paths from key team members to each node, then check code repositories, dependency sources, build trigger windows and artifact destinations. The guidance below describes common collaboration patterns and does not replace your team’s own continuous testing.

SG · Singapore UTC+8

Best for Southbound Asia-Pacific and Southeast Asian teams

Commonly used for daily development, dependency installation and build-artifact transfers for teams in Singapore and nearby regions. For teams spread across multiple Asian time zones, it can be a strong starting point for a shared queue.

KR · South Korea (Seoul) UTC+9

Best for teams in Korea and nearby regions

Suitable for interactive development, remote graphical interfaces and short test cycles focused on Seoul. For frequent Xcode use, also monitor keyboard and mouse response, display stability and file-sync time.

Often used by distributed teams to share a build machine and centrally store sanitized logs and output artifacts. Do not compare a single ping; test office networks, home networks and automation-runner paths separately.

Models & Node Catalog

Three configurations across six nodes

The matrix shows fixed catalog relationships only: all three configurations are available across all six nodes, for 18 combinations. “Plentiful” indicates catalog availability, not a reserved device; live console results apply when you place an order.

Network Sampling Log

Review P50 and P95; do not choose a node by its single lowest value

Each cell shows round-trip latency as P50 and P95. P50 represents the typical path; P95 highlights congestion, detours and peak-hour variation. Use these figures to build a shortlist, then repeat testing from your team’s actual egress points.

Node Selection Decision Order

Put networking, dependencies, schedules and data requirements on one run sheet

A nearby node with slow dependency downloads, or low interactive latency paired with a long artifact-transfer path, can make the complete task slower. Collect comparable data in these four steps.

  1. 01

    Sample the real networks of key team members

    Sample P50, P95 and packet loss from office networks, home networks and automation runners. Do not use one team member’s one-off test to represent the whole team.

  2. 02

    Measure repositories and dependency sources

    Record Git pull, dependency resolution, cache restoration and artifact-upload times. When build inputs and outputs are concentrated in one direction, end-to-end data paths usually matter more than keyboard latency.

  3. 03

    Align CI triggers with manual review hours

    Track when tasks enter the queue, when failed tasks need manual handling and when artifacts are delivered. Make the node serve the main working hours instead of simply pursuing the shortest map distance.

  4. 04

    Confirm data-processing requirements

    Confirm where code, logs, model files and media assets may be processed, and define export and cleanup procedures. If a project has explicit regional requirements, satisfy them before comparing performance.

Cross-Time-Zone Collaboration

Keep the device working continuously; let members continue from handoff records

Teams across Asia-Pacific and North America can schedule queues and handoffs around the same dedicated physical Mac, but should not share uncontrolled credentials. Every handoff should answer: where is the task, where are the artifacts and what should the next person do?

Asia-Pacific working hours SG · JP · KR · HK

Prepare inputs and submit reproducible tasks

Pull a fixed commit, lock dependencies, and document build commands and expected artifacts. Before queuing a long task, record the start time, working directory, log location and baseline resource usage.

  • The submitted version matches the dependency lockfile
  • Remove tokens and personal information from logs
  • Retain the exit code and minimal reproduction steps for failed tasks
Handoff record 1 task sheet

Handoff by status, not verbal messages

The handoff sheet should include the current stage, latest successful time, outstanding blockers, artifact checksum and next command. While background tasks continue, specify the process ID and stop conditions.

  • Current branch, commit and build number
  • Completed, failed and pending-review items
  • Owner responsible for revoking temporary credentials
North American working hours US-E · US-W

Review outputs and write back traceable results

The next person should verify the node, current user, available disk space and task status before handling failures or exporting artifacts. Update the task sheet when complete; do not replace text records with unsanitized screenshots.

  • Verify artifact size and checksum
  • Record build time and peak resource usage
  • Clean up temporary files and unused sessions
All nodes operate normally 365 days a year

Cross-time-zone scheduling can continue around build queues and manual handoffs. If a task is highly dependent on an external service, repository or reviewer during a specific period, record that constraint in the task sheet rather than assuming node location will eliminate waiting.

Multi-Node & Migration Consultation

Provide the source node, target node, time window and data volume first

If you need to move existing work to another node or arrange a multi-node workflow for different teams, provide enough operational context. We will first check catalog combinations, data-movement methods, interruption conditions and access permissions, then confirm the information needed next.

01

Source and target nodes

Use the SG, JP, KR, HK, US-E or US-W identifier, and specify the current and desired models.

02

Desired time window

Provide the earliest start time, required completion time, time zone and acceptable task-pause duration.

03

Data volume and type

Estimate the capacity of code, build caches, models, media assets and output artifacts separately; do not send project source files.

04

Validation and rollback conditions

Explain how migration completion will be verified and which logs, artifacts and original task state must be retained if it fails.

New Projects & Multi-Node Planning

Email the purpose, number of concurrent devices, candidate nodes, expected duration and data volume. Do not send passwords, complete private keys, payment credentials or unsanitized code.

Prepare a regional consultation
